Just got back from the store. Idk I'm just pretty annoyed.

I had to go to the store and pick up a few things for work as well as a couple things for myself. When I got there, a couple of people were in the store wearing masks. I want to say 5 or 6 people. I'm just guessing. I'm not really paying attention. I do my shopping. At this point, only one person is left in the store. I go to go pay for my stuff... and the cashier is *not* wearing a mask. They look right at me and say "oh sorry I don't have a mask on." I don't care if you have a mask on or not, but it just seems a little counter intuitive that you're working in this store interacting with people *and* you are the only person without a mask on. I just say "that's fine" and they go about their business. At one point, they ask me if I need a bag. I say yes. They hand me the bags... but *don't cover their mouths*. I look at the bags. I open one up. I look at them... and I say, "don't you need to put the stuff in the bags?" The cashier just kind of laughs at me and they start putting my stuff in the bags. I swear I'm not making this up. I just kind of look at them and say "You know your not supposed to be breathing in my stuff, right?" And they say something along the lines of "I'm not supposed to be breathing on your stuff." Like, hello. I'm just trying to do my job here. I just kind of stand there for a sec and then I say, "Well, I'm outta here." I grab my stuff. I leave the store. And that's it. That's my vent.
