This is often the least nasty surface in a bathroom stall to snort drugs off of. It speaks to his class character that he'd rather do lines off a toilet seat, where you risk losing drug into the toilet bowl itself, or onto the floor, and not just using the poor man's snuffbox (the crook between thumb and forefinger) to hoot lines out of. The rolled up bills people use to do rails with are nastier than any toilet seat, anyways.

Cocaine doesn't lend itself to sound judgement, but RFK Jr. is the kind of guy you could sell crushed up no-dōz to for $200/gram and have him blowing up your phone the next day looking for more. Speaking strictly as a substance enjoyer this guy is a tool.
