We went to ihop for sunday brunch. We waited forever for our food, the waitress who was waiting us gave my crying baby sister pie to calm her down, and got us something i cant remember what it was ( this would all be deducted from her pay). After the food (we always do this) we debated about how much we should give her, since she was so generous to us we would be to. The amount totaled over 75$'s, we left it on the table, and we left. We were about to pull out when this waitress came to us crying. She told us she was having financial problems, and she was praying for something like this. We all felt very good afterwards.
tl;dr: tip your waiters, and waitresses
