It seems to be a mission for some people to fight to have all the windows on the bus closed, for all of every journey? Why? Before covid this wasn't an issue - now it seems people have a point to make.
I get there can be a chilly draught, but just put your coat on, or put your hood up?
I am immunocompromised, and wear a mask and open the window on my way to and from work. Every single time I get ill, ( currently a couple of times a month) my classes are left with non specialist agency staff. I take all the precautions I reasonably can to keep from catching anything, but this constant battle on the bus every working day is really wearing my down.
