I once had a roommate who thought it was perfectly okay to lick off the tip of a condiment bottle. He did this at home, which was bad enough, but he also did it at fast food restaurants. Ever since then I've always had a hard time using condiments at fast food restaurants which use condiment bottles instead of disposable packets or self-serve pumps with cups or whatever, because now I assume that lots of people do this shit.
Anyway, stars are for this woman's party description reminding me of this thing that I have never been able to scrub from my memory.
