You get what you pay for, what did you expect? Someone who can talk intelligible would be able to get a job that pays a dollar more. If he can write, two bucks more. If he can think past his next lunch, he's promoted to store manager.
Interesting since everyone I worked with when I worked at a Gamestop was in college at some stage including myself. If you don't want to do much except talk about games and ring people up for a few hours a week, it's a fantastic job.
Never let someone who says it cannot be done interrupt the person who is doing it.
