It might be because I'm out of tolerance for a lot of things at the moment but I've had enough of the 'but my face gets hot' and 'couldn't possibly wear one for 2 ours straight' brigade.
Barring medical exemptions, I think people just need to suck it up.
I wore an FFP3 mask at work day in day out for hours at a time for years. Yes, it's weird at first and it gives you spots and makes your eyes dry and sometimes your lips dry, but your body will adapt if you keep at it. (honestly, be glad it's not a rubber half mask or a powered respirator, both of which I've also had to wear all day for years and are grim/loud respectively)
If your glasses are fogging or it doesn't fit right try a different type - there are lots available. Mouldable nose strips really help with the specs.
You will need to speak very clearly when you talk so you can hear each other (I know it's shit if you have hearing loss - that is a situation I still have sympathy for).
Honestly, get one/a style that fits you properly, and get on with it, you'll get used to it. It really isn't that bad, and will save lives!
So... YANBU = people need to mask up and get over it
YABU = masks are the worst and comfort is more important
