I'm exceptionally rude to people at the tills who are rude to me. It's horrednous customer service to try to take the piss out of your customers, and the best thing about it is that I can verbally maul them without it sounding like I'm being an overly rude person (see Dreddz jokey checkout girl). Seriously, you can say anything with a smile and people think you're just having a laugh. Good fun.

I was in PC World asking about graphics cards, and the guy who sevred me was horrendous. He didn't listen to me when I was telling him what I wanted out of him, instead choosing to just point me to the most expensive one. smurf off, moron, I'm not an idiot. Then he just started going off on one about his monster PC with 500 million graphics cards in it, and 87000GB RAM, and how he liked to snipe people on CoD (if anyone's wondering, his name is "C4_Miles", y'know like see for miles, because I see for miles YEAH THANKS DUMBASS I GET IT ). It was the worst shop experience I've ever had, just because it's so horrifically bad. He then decided to take me away from the £100 graphics card he was promoting and instead showed me the "cheap" £600 PCs they had. For the record, I neither asked nor hinted that I wanted a new PC. It was truly abysmal customer service, and this guy was an immense stereotypical gamer. I can't stand those sorts of people. Games are for fun. Go kill yourself if you think any different.
