I used to be a private investigator and I was in another city on a surveillance. After sitting in my car for 12 hours or so, I was famished and wilted. I went to a favorite restaurant that I tried to frequent every time I found myself in that city. To be honest, I probably didn't look the part to eat in this place after spending all day and half the night sitting behind the steering wheel with a camera in my hands. Anyway, the waiter took one look at me and that was the end of service for me that night. This particular restaurant was known for their croissants. Every table around me got hot croissants; I got squat. My wine glass stayed empty for most of the meal. The waiter would walk right by me and I'd call his name; he'd just ignore me. Those are just the high points. The whole evening was a disaster. I tipped nothing. First and last time I have ever done that. I also had a conversaiton with the manager before I left. He gave me some gift certs to use on my next trip, but, how useful is that when it isn't your city?
