Working in a supermarket I can report the worst experience is the deliberate 'open coughing'.
I've had three lately. Number one, this man in his sixties, walked past the registers, dropped in a big, exaggerated cough, then shot me a smugly aggressive, 'what are you going to do about it?' look.
Two, this silly old man, with his wife. She mentioned the virus and was giggling and he thought it was funny to mimic being ill with it. This involved open coughing, right over me.
Three, the worst of all. This dad, about 27, had a toddler in his arms who was throwing a wobbly. I opened up another register for him but had to get up and unlock the gate so he could unload his stuff. As I reached down for the lock on the gate I gave him a subtle hand signal for him to stand back a bit, so his kid wouldn't be wailing right on top of me.
He then threw his own wobbly, obviously offended by my safety-first approach, and proceeded to call me 'pathetic', and followed-up with another big, exaggerated coughing fit.
He then ranted about the 'conspiracy'. Apparently, the Government has had a vaccine for ages, but won't release it'.
Out on the street, a friend was deliberately coughed over by a fat, 23 year old on St Patrick's Day. He'd just got back from the pub, she was out using the shopping centre's hand sanitizer whilst on a walk, he made a joke of it, and let rip.
For balance, here's a couple of examples of women behaving badly too. One, an older woman, asking me something silly when we're extremely busy, I step back to get some space before answering her, she jabs me with her phone and says 'hey! I'm talking to you!'
Two, yesterday, this old bag was asking for the tenth time in a minute when the toilet rolls were coming in (she knows the answer) I was at the register, she then came within a foot of my face with an aggressive, 'Helloooooo! Hellooooo! Is there anybody there???!!!!!'
She thought it was funny, as she was playing up with some other older women in line. They didn't quite look amused.
Fun times. This sure aint bringing out the best in a lot of people.
