Masks are to be worn. Guy ahead of me (Russian/Bosnian?) wasn't wearing a mask, was asked to provide his info. Upon stepping to the window, was asked where my mask was. Told clerk I have a Medical Exemption. Was told to return and stay in my truck and given a number to call. That's fine. Got a door immediately but wasn't started for 1 hr and it took over an hour to load.
