It's been a while since I've been to the post office. Went this morning, a line of 10 or so people in the small lobby and the lady in front of me has her mask down. I ask her to put it on (nicely) she says she doesn't have to wear so she's fine and she points to a sign. And omg there's a sign that says masks are optional?! WTH Are your USPS doing that too?
