"I know lots of people think we should tip, I don't, and I applaud this guy for leaving a DVD,"
You eat out a lot? I bet not at the same restaurants more than once or twice.
LOL, how true. If not, this person has eaten their share of spit or worse. Years ago, when I was in college, I worked in restaurant. One of the waiters was nuts. I'm talking Joe Pesce/Goodfellas nuts. He had a party of four. Before they even ordered, someone in the party made a wisecrack to the waiter. The soda machine was off to the side. I saw him with my own eyes, spit in all four glasses. He caught my eye, and my blood ran cold. It's not a myth, waiters really do these things.
