Several things wrong here. Got a $20 gift certificate, found out I couldn't use it at the bar. Went to play pool, and managed to score a table for $15 an hour, then when I went back to the counter to pay, I have them the $20 gift certificate and they used it all at once. Didn't give me back my $5, so I paid $20 for a $15 session of pool. That's basically stealing, and on top of that, the woman at the counter gave me attitude.
