I work in a assembly plant and you have to wear a mask at all times, except when eating and drinking.
Course they shut the cafeteria down, so only vending machines.
I wear my mask all day sitting at a desk in the middle of the factory floor. All workers have to wear them too.
The ironic part is, the salary people in the comfortable and cool offices don't have to wear them while at their desk.
I am however, getting used to wearing this thing, so now it's no big deal.
I frequent the PX and commissary on a military post and it is mandatory to wear mask in any and all facilities.
