How much does customer service affect your decision to buy something?

The other day I was in a bar at happy hour with a friend. The bartender was talking to a coworker about the other girls who worked in the restaurant. He said stuff like “Sarah has a big ass but an ugly face,” and “Megan is always wasted.” Any time my friend and I needed something, it was hard to get the bartender’s attention because he was talking to the waiter. The manager kept checking on the bar area and chatting with the two employees.

We really wanted to get tanked and eat some greasy bar food, but we ended up leaving to find another place because the service was so lame. I’m not usually uptight about stuff like this, because I’d rather just enjoy my meal and talk to my friends. This bar was a problem because we had long waits for everything and the bartender was having his conversation right near us. Is stuff like this important when you decide whether to buy something? What about great customer service- does that encourage you to give a place your repeat business, or does it not really matter?
