Assault. Does this question ever wind up with answers that don't hit the bottom?
Despite the normal safety measures + an intentional lack of flirting when the vibes weren't there, public space, no booze on first meeting, split the check so there are no "implications", no physical contact. Dude didn't like hearing no as I wanted to head to my car and leave. Fortunately, it was in public and he tried to keep it low-key but I had deep bruises on my arm for a while.
