Yep. I completely understand how shyness can make you come off as snobby or boring, but not this. I'm terribly shy, and saying 'thank you' is such an automatic reaction for me I think I say it too much. I can't imagine what was going through this person's head! There's having poor social skills and there's, like, not interacting with humans.

I cannot imagine allowing someone to pay for EVERYTHING either....
