I wouldn’t expect my son to hang out at places that put him at risk of such a possibility, and especially at a place inhabited by homos.
Personally, unless a drink comes from a licensed Health-dept approved vendor, a closed beverage container from a licensed distributor, or a very close friend or relative, I ain’t drinking it. You’re an idiot if you do.
Unfortunately, those places include “any bar or celebration with drinks” these days. Predators (hetero, homo, whatever) do not walk around with convenient labels and one’s personal ‘radar’ may not detect them, even when all parties are sober.
