Hey beat the geisha mission and was walking around the bar and accidentally accepted the geisha mission again. i really dont wanna play the same mission all over, is there a way to quit a mission and get back to the bar?

This is the same problem I'm having except its w/ that Bunny mission.

Yea, it looks like we're all stuck.

I've got the same problem with the bunny mission. I'm definitely not doing that one again, it's too weird.

Has anyone got a solution for this problem?

beat it. only takes around 20 minutes. earns you more respect points anyways. To avoid this incident happening again. I would suggest to make a second save file in you profile when you arrive at the bar/dojo. Incase you re accept a mission, you can simply exit that game and load another saved file.
