<human>: Can you succinctly summarize the text in 1-3 sentences?

So I went into this local bar that only accepts cash and their ATM was out of order. I asked him if they were accepting credit cards to amend for the disabled ATM. His response was a huge over reaction and he came across as a huge ass hole. I went to another bar and got some money, had a beer, was a little upset by the whole situation. On my way back, the bar was on the way and I decided to stop in for a beer. The bartender came up and I ordered a beer that was on special, and he came back and said "The Supper Club is on special, but I'll give it to you guys, for, let's say half off." And gave us two beers at half the price and chatted us up for a while, which totally redeemed him in my eyes. Not the best 'redemption' story, but you get the idea! Let's hear it!
<bot>: Bartender was total ass hole, but redeemed himself later with a sweet beer special and conversation. What's your best redemption story?
