What kind of crap did you put up with while waiting tables?I worked at a 50's style diner all through high school and summers I was home from college. Some of my worst customers were regulars.One guy would always order his meal to go, and always paid with a $10 bill. After he had paid and left, he'd wait a minute, come back in, flag someone down who wasn't the person who he paid, and say that he had been given change for a $10 when he paid with a $20. I caught on. I "hid" and waited to catch him, and then popped out and said, "no, he paid with a $10. Open the cash register, I marked the bill he paid with with a red X." Then I warned everyone else about his stunt and to watch him.One family always came in after church and would show up before we opened and bang on the door. The guy would always pay with a $100 bill after every single week we told him we didn't have change for a $100 when we opened the registers with only $50 in each of them, and the manager would make change from her own wallet. The father would order one fewer drinks than the number of people in the family, and then tell someone other than his server that his server had forgotten a drink to get out of paying for it. One time the mom ordered a hot dog for her young son, and then changed her mind and decided she wanted to feed him a grilled cheese instead (probably because she saw that it was cheaper). She asked me to change the order if it wasn't too late, but their food was already ready. I brought it out to her, and she said, "oh,I said no mustard. Take it back and just bring out the grilled cheese." Meanwhile, her son was saying, "no mama, you said mustard and ketchup." Yes, she sure did. Your mom is a liar, little boy. And you all just got out of church. Awesome.
