Exactly this. I had a character go to a brothel in a campaign I ran. I just said okay, you go to the brothel and have whatever you consider a good time. No further detail or RP was requested or required.
The bouncer is a God. The DC is 500. Crits are the only way through. There's an instant kill atmosphere in the front room that requires all elemental immunities to survive. If they make it past all of that they are disintegrated by the unfiltered visage of a naked god. I hope they brought another character sheet.
great, what the players don't know is that the bouncer is a trickster god in disguise and they simply will not ever get past him, and they can have fun throwing themselves at a brick wall repeatedly while everyone else carries on with the actual campaign.
Except that's the point, they will not be having fun. Nor will you, nor will any of the other players. Because that setup is not fun. And presumably you're hosting a game for your friends with the intention of everyone having fun, so it's best if you find another tact.
