Yeah not my cup of tea as a scenario either unless the model and room were very engaging / "energetic".
Was she new? I have sometimes seen newly minted models with no tip activated toy (fair enough of course) and also no tip menu. Sometimes not even a wheel set up.
A bit like going to a restaurant without a menu. I do not expect to have to ask (or guess) what food is offered and then also have to ask how much each such offering is in a restaurant, likewise I do not accept it in a cam room.
Naturally, as you know, in these cases, we are free to just scroll to the next room
