This isn't as much bad service as it is bad machines and customers, but it still is terrible service.
My dad and I wanted to hit some golf balls, so we went to a local golf club/driving range. Right when we got there, there was screaming kids all over the place. We decided to go in there anyway, without much as a second look. Big mistake. Some bratty teenager complained to us and then gave us the ticket. We went to the machine and golf balls started spraying out at us! All over the place without warning. We really wanted to hit some golf balls, so we hastily went up the stairs to the top of the driving range. The tee sucked, being way too high and on a angle. We had a lot of trouble and got really annoyed. Just then, one of the golf teachers gave us a sneer and started laughing at us. His tee was perfect, of course. Just as my dad went over to clobber his head off, some golf guy start's talking to us. Now, he did show me a good way to hit the golf ball, but he wouldn't stop talking and cursing for a second. He distracted me, and I ended up hitting suckishly. He was trying to clobber it as hard as he could, over the net. I still had a lot fun, but thanks to sucky service, it sort of sucked.
