That reminds me of 2 stories about one of my regular crabby limit players. I know, redundant...
One day he was checking his hours on our kiosk and said that it didn't update from his play that day (he had gotten up about 30 minutes prior). He was starting to get upset and I was trying to calm him down and check it out on my end. I figured out that the dealer clocked out the wrong player. This guy usually sits in Seat 1 or 10, but this time was in 9. The dealer clocked out seat 10 instead of 9. When I looked, this guy was still on the game, which is why his hours didn't update. So I explain to him what must have happened with the added bonus that he got 30 free minutes! Whoo-hoo!! But he was still pissed because the dealer made a mistake.
Another day the same guy came up and had a question about his comps (we give 50 cents/hour). He didn't think his comps went through the day before. He played 7 hours but he only had less than $1 additional on his card. He keeps complaining that things aren't working right and we should fix it. As I get into the system on my end to investigate (and note that he has $350 on his card) he finally adds a bit of information to the story...
