Ok I was in Walmart buying a video game when this dud eshows up and immediately questions my selection. Like it's some kind of internet forum!
I dunno, but I just said "That's great, bro" and left.  Then he follows me to the checkout counter to continue giving me crap about it.
Well I just got incensed with him and told the clerk to do something about him or I'm not shopping there anymore.  He was told to leave.
