Had to up my mask game this afternoon. Went into the store at the Chevron station and was immediately yelled at by employees: put on a mask or get out. I said "medical condition" and grabbed the stuff I wanted and came to the counter. The guy said I still had to leave, so I said "I'm under doctor's orders to not wear a mask, so you can't make me leave." He agreed, and said he was tired of arguing earlier in the day with other people claiming "medical condition" but it's cool since I have doctor's orders. :-)
