It's not the worst, but certainly not a pleasant experience at least in summer or winter. In summer your face gets all sweaty and disgusting and in winter I get a runny nose and the mask gets disgusting. If it's not really necessary I'd rather don't wear it.
It's funny. I didn't understand these sorts of complaints until I remembered I have a beard. There is always something on my face and I'm just used to it.
It's the worst thing for me. I know there's elderly, immunocompromised, and poor people who would be devastated after a serious illness. But I worked really hard at my office job and I need to see people smile because that's important for some reason.
