@merpreb I just did that on Monday, when getting labwork. I purposely set appt for 8:15, first of the day. That lab has set aside first hour for those at risk, with appts. Here comes a rather brawny young man, posturing, no appt, no facemask. Before he even got "into my space" I asked him to get a mask. He said "Says who?" and I pointed out the requirements on the wall next to him. He told me I was rude; I told him I was following their rules, and he needed to, also. The lab tech heard the whole exchange, and sided with me. Sigh...
