Bee in the beer of a crude coworker, do you warn them or dummy up?

Say you are at a company pic nic or BBQ and one of the supers who is really nasty, snide, egomaniacal, Boorish, and snobby is sitting near you and leaves to go use the restroom. While away a bee circles his/her beer can then goes down in it undetected by anyone but you. Then said butt nugget super returns from the restroom makes some crude joke about you trying to steal food off their plate because you don’t earn as much and thus must be poor. Would you say something about the bee in the beer, would you say nothing, would you secretly hoped the bee did not drown and sting the s*** out of them, or they swallow it and get their throat stung, would you slap the beer from their hand and use the bee as the reason?
