Anyways, sure, it is a possibility that my guy knows some guy who knows a guy whose brother sells coke. Then again, with those degrees of separation at play, I'd be surprised if we didn't all know a friend who knows a friend who knows a friend... It's a small world. Therefore, you snowball argument, essentially a slippery slope of drug use, is inappropriate in this case, and in general that's been proven to not be the case—that is, people who smoke week usually only smoke weed, and do not progress onto something "harder" (in fact, medical marijuana has helped people with their addiction to opiates; trust me, I'm not someone who thinks weed is a cure for everything, but your characterization of it, I think, is undue and unsubstantiated).
But yeah, I also think it's a bit crazy to condemn this particular instance of "taking" food while, at the same time, thinking recreational drug use at some level is okay. When you think harder about it, unless you're obtaining weed or your drug of choice ethically (which, unless it's through legal means, you're not), smoking recreationally is definitely on morally shaky ground, whereas this apparently innocent taking of food is not. Then again, we're not expecting ADCOMs to conduct deep ethical analyses on each IA case, which is why generalizations are made in the first place—regardless of their accuracy on the whole.
