I dont know if it helps, but I dont think I would be bothered to be asked to stand up for someone to pass:)

I would be kinda bothered to see an empty seat though, cuz someone could be sitting there (even if it isn’t me, it’s still better if the bus has fewer people standing).

(I suppose some people might have their reasons (like medical issues) and might want to seat alone, so I can’t be very bothered about empty seats, as I don’t know for sure their case.)

Also, you can stand up if you are approaching your stop (like maybe when your stop is next), to lower the chances of having them sit down and stand up.

PS. I’m the guy who doesn’t tend to sit down, mainly cuz there aren’t many seats.😆 If it’s packed, I might stand next to the door to step down the bus during each stop to help with the flow of people:)
