[Quick background: I pre-ordered Tomb Raider, bought it, decided to exchange it. I figured my $60 would be better spent on other games, MORE games, and I've been wanting to play No More Heroes for the longest time.]
So I went to go exchange Tomb Raider for No More Heroes on PS3 at GS (I'm never gonna get around to it til the price drops start coming, anywho...), and the guy there is a middle-aged man with an english accent and proceeds to brand himself as a less-than-adequate sales rep by laughing in my face and repeating "WOW...wow...WOOOOW, you want to trade this in for THAT?!?"
I look the man in the eyes and hold back from opening a can of whoop ass, telling him "Yes, I'm exchanging this brand new game which I can easily find later on for THAT game which is harder to come by (in my area). That's it."
So he manages to shut up for a couple seconds while the other child of a GS cashier just stands behind the counter; motionless, quiet. He wouldn't bother to acknowledge me even when I first came in approaching the counter, asking him to help me while the other guy was still busy on the phone.
The silence ends as he abruptly begins to yammer on about how great Tomb Raider is and how the game I'm exchanging it for isn't even good. The entire exchange transaction seems to come to a crawl as he continues muttering to himself and punches keys in one...by........one...and one more....wait.....hmmmmm....*tap tap tap*
Process comple-
"So do you want to do anything else with the difference? Like pre-order this new game..."
"No. That's all"

"Oh but you'll want to get Destiny..."
"Not yet"
"You'll definitely want Ass Creed IV. Come on, you know you want it!"
"No man. That's it." :|

"Oh hey! It says your card is expiring soon, do you want to renew?"
"No thanks. I'll do it later"
"Well you know you saved over $$$ amount this year, you're gonna want that card again." *I spaced out for a second*
"It's ok, I'll do it later"
Finally, he hands me the game and my change but keeps the old receipt. Now out of the dozens of GS employees I've dealt with I've always been given the old receipt back, so I simply ask for my old receipt back (I like to keep track of all my spending down to the penny). The ever-so-helpful soul refuses.
"I can't do that. I've taken the game back, so I must keep the receipt!", he retorts.
"I've always been given the receipt."
"Well I can't do that, you probably just want it for the codes huh?" (I've had the receipt for a day, I think I could manage to use them beforehand.)
"No, I like to keep track of my purchases."
Now this had become a personal conflict of "I'm tired of your shit", so I asked for it again. He proceeds to take the receipt, rip off the lower half, and hand me the piece with the codes. I swipe it out of his hand, glare at him, and walk out. As I'm exiting, I hear him smugly say "Thank you!"
I was tempted to go back in and shove his foot down his mouth, but decided against it since...well...there are laws against that sort of thing and I have a conscience.
