Hehe! What fun! The only other pitting I recall recieving was one I gave myself. I can finally consider myself to have truly made a difference at the Straight Dope. Cigars for everyone, it’s celebration time! (Don’t worry, they’re bubblegum.) 
For the record, imthjckaz is absolutely correct. I am indeed a student currently attending that college.
Ok, let me get something off my chest right away. Lola, hon, it’s one thing to get angry and pit someone, but it’s quite another to get so rip-snortin’ mad that you make several typing errors and require several follow-up posts to fully expound on your irritation.
Especially when it’s about something relatively mundane. Yes, mundane. I haven’t killed anyone, raped anyone, kidnapped anyone; nor do I drive an SUV. (
) So, I guess what I’m saying is, in the best interests of your own mental health, chill.
There’s a lot of material I could address, but I think I’ll start here:
For most of my life, I only rarely got to eat in sit-down restaurants. Pretty much only when it was my birthday or the birthday of someone else in my family. When this was the case, I did not pay for the meal.
A little later in life, when I actually had a little money of my own to spend and therefore purchase meals of my own, I ate almost exclusively at fast food restaurants where tipping is not expected.
I cannot afford to eat at sit-down restaurants on a regular basis. I wish I could. When I do, it is often someone else who is paying. Add that fact to the fact that I’m quite absent-minded in general, and it’s an easy recipe for forgetting to tip.
That said, even when I remember I don’t always do it. I sometimes have barely enough money to pay for the meal itself. Sometimes the service isn’t that good. Even if I were a millionaire, I wouldn’t leave a tip for bad service.
