I would say 80% of people I saw on the bus were wearing masks. However, many took them off once they sat down.
I feel for the drivers.They are not paid enough to be bouncers refusing entry or taking abuse. There needs to be someone else on the bus with them for support.
That’s not what I saw on the buses. I know some are medically exempt but I would say I saw at least 40% without face coverings on buses.
