Our waiter told us if we ate everything off our plates, we'd get free cookies. At the end of our meal, he said I wouldn't get any because I chose not to eat a piece of lettuce that fell onto the table, which was built-up in layers of gross, sticky grime.
He again stated I'd need to eat the lettuce, if I wanted my free dessert. I asked if he was kidding, to which he answered "NO" in a rather snotty attitude. I said I wasn't going to eat the lettuce, because it was unsanitary and I didn't really want a flipping cookie anyway. And I mean, how often are those wash rags that they use to wipe the table actually cleaned?
No tip for him...
