I once went to the Purple shirted place with my girlfriend's grandmother (to buy an el cheapo laptop.. not my recommendation) and had to listen to a member of staff peddling off paragraphs of crap.
Basically, saying you NEED this, you NEED that, you NEED the support.. I was turning a blind eye because I was tired and he wasn't making eye contact. Eventually he started going off on one saying how it took him 4 hours to fix a problem in Vista.
At which point I said, "listen mate, we only came for the laptop, if there's a problem and I can't fix it, then no one, especially not someone in India is going to be able to fix it".
His face was a picture.. made worse by the laughing from the old lady
