Who is wrong? The Server or the 'Pastor'?

Daily we struggle with the art of manners, hospitality and self-control in service. Those we serve are not being paid for their behavior and thus execute less of the constant self-editing we are conducting at all times. Whether it be making coffee in plain view or discussing a guest issue with a manager; the language, gestures and facial expressions will vary greatly if a guest is in view/earshot or not. Occasionally, slips occur-typically when a guest sneaks up on you mid-expletive and mid-rant, but for the most part we keep a respectable level of distance between how we really feel and how we are perceived to feel. I often have fantasized stern 'talking-tos' to some of my clientele explaining to them how they seem to make it their goal in life to make my impossible day harder (yesterday I think I gave about 5 of those talking-tos...3 to the same person). But a story yesterday forced me to seriously think about where the line is between service justice and whining. An incident at an Applebee's was reported by Huffington Post where a girl posted a credit card receipt on Reddit from a guest who stiffed her and left a snide remark on the slip. The deplorable guest saw the Reddit post and proceeded to turn this girl into her employer and demand her job, leading the girl to get fired.
As the general public is in defense of the waitress, who in-fact is the guilty party? I'm sorry my fellow service employee, but the waitress is the faulty party here. Let me explain: In almost all corporate restaurants staff members sign confidentiality agreements upon hiring for various reasons, but one is because they handle transactions using people's credit/debit cards. In some cases, even codes of conduct expanding to facebook and other internet sites are included on the agreement. The waitress may not even realize she signed such a form since the hiring paperwork is extensive and usually done faster than legal wants, but slower than payroll wants...and as we all in service know-payroll trumps legal every time! On that alone, the waitress, 'Chelsea', is subject for termination for posting guest information online-thus also, the Applebee's formal statement in the article.
In addition, some restaurants (at least every single one I've worked in) have rules regarding discussing tips in front of guests. This situation would count as discussing a tip.
Now, I know my feedback my seem unsympathetic to a sister in service and to her, I'm very sorry you got fired. Even though I would have fired you even without the customer complaint. I would have fired you for taking home and taking photos of personal customer information. I don't care if their credit card number was on it or not-the slip is not your property and you are potentially stealing from the restaurant and from the guest.
I still seem harsh, do I? Here's the deal folks, this isn't a 'poor server got stiffed' story. This is a 'server is being unprofessional' story. We all get stiffed and snide comments sometimes! This is not new, this is not revenge-worthy, this is NOT going to change, this is the SERVICE business!!! What? You thought you were going to get a waitressing position, look cute, make lots of tips and live the high-life? Its true to a degree, you can make a decent wage, but you're going to take the hits. You're going to get stiffed, you're going to get felt-up, you're going to have to deal with creepy men and if you're worth a damn-you're going to walk out the door with a little wad of cash, go to the local pub with some co-workers and bitch about the day. Start taking your cues from Mr. Bates and not O'Brien because you have no recourse here.
Do not be confused, I'm not on the side of the alleged 'Pastor Bell'. His behavior is highly questionable behavior of a pastor, which is why I'm not even sure he is one. Matthew 22:36-39, "Teacher, which is the great commandment in the law?" Jesus said to him, "You shall love the Lord your God with all your heart, with all your soul, and with all your mind.' This is the first and great commandment. And the second is like it: 'You shall love your neighbor as yourself." A message reiterated in Mark 12:30-31 among other chapters. In addition, I offer you Deuteronomy 26:12 'When you have finished your harvest, reserve the tithe in the third year (the year of the tithe), and give the entire tithe to the descendants of Levi, to the foreigners, to the orphans, and to the widows, so they may eat and be satisfied in your cities.' to remind you why you tithe and 1 Timothy 6:17 'Command those who are rich in this present world not to be arrogant nor to put their hope in wealth, which is so uncertain, but to put their hope in God, who richly provides us with everything for our enjoyment.' for you to remember that God provides even for your enjoyment. Eating out is not a necessity, but a luxury in which you are aware of the responsibilities that go with it. Does God not provide for you? Are you bitter at the amount you tithe, because Proverbs 23:5 warns us, 'Cast but a glance at riches, and they are gone, for they will surely sprout wings and fly off to the sky like an eagle.' Your stingy behavior also has repercussion. I recommend the next time you have an issue with the gratuity, talk to the manager.
