Tl;dr group of pricks come on my bus home with ltr. Dominate the atmosphere and kill the vibe with the ltr. Who has been succsessful in this scenario?

I was taking my LTR home from a great night out in the city. The mood was good, the night had been fun and the only unavoidable strain on the night would be the bus ride home.

We get on the packed bus when a group of teenagers (19yo) fill the seats around us. Theyre drunk and rowdy. The alpha of the group starts talking to his mates loudly about sex, other girls and their plans to hit a pub when they get off the bus. Everyone is on this bus for at least an hour.

Their presence dominates the bus with the alpha eventually pissing into a bottle, closing it and rolling it down the aisle. A trio of 18yo HB6's give the guy their numbers (textbook red pill)

They completely ruin the vibe i had with my LTR. I cut my losses and call it a night.

Has anyone here had any success in a scenario like this? How do you deal with a group of pricks in front of a girl?
