eh, as someone who was one and has been surrounded by wreckheads my entire life, this is absolutely not my first thought if someone doesn't want a drink or whatever. Also, compound cultural inputs - I'd full understand someone with a non-European family name not wanting to imbibe booze.

I'm perfectly ok with someone not wanting a drink. I wouldn't want to go out on the piss with them, mind, and I fully understand and respect the fact they'd not want to anyway... .
