Most of the calls will be idiots that don't know that you have to plug things or charge batteries in order for them to work.
I overheard a conversation a week or so ago, and some guy who had worked at Best Buy was saying how he had a customer bring in his laptop and say it wasn't working, OMGFIXITRIGHTFUCKINGNAO, that kind of thing. Best Buy guy plugs it in and it works. Customer is like, "yeah, well you plugged it in! I paid more for everything to be WIRELESS."
I lol'd. Then the people talking looked at me and I'm like, "sorry, that was GOLD though. I love stupid people stories."
