AITA for not paying for the Uber's cleaning fee?

My BF has been friends with this guy for 15 years and they routinely hang out together. I really don't like this guy, he's racist and misogynistic and is always passing his statements off as a joke. It would make me very happy if my BF stopped hanging out with him but I don't want to be a bitch and tell him to stop.

Last night we went out drinking together as he was visiting my BF, he continued to make "jokes" that were racist, transphobic, sexist etc. and it was an awful night. My BF doesn't seem to have an issue with anything he says even when he uses the n word (my BF is black and his friend is white). He even made a lot of jokes at my expense that I wasn't happy with at all.

We were all staying at my BFs place so his friend got us an Uber back. I wasn't feel well and I was a bit drunk and I ended up puking in the back of the cab. I apologised non-stop to the driver and offered to clean it up. My BF got a message from his friend today and he was charged $150 for the cleaning fee. AITA if I refuse to pay him back? My BF is saying I am.
