I went into a Walgreens in Chicago, and waited in line behind two other people. There was a cashier free but the person in front of the line was waiting to be called. The guy behind the person in front politely said,
“ma’am, the cashier is free”
‘I’m waiting to be called” was the response.
So the guy behind her just walked past her, and she pushed him and said,
“Careful buddy, you’ll get shot for doing something like that”
I was taken aback at how quickly a simple discourtesy escalated to shooting someone. It just blew my mind that shooting someone over queue jumping was verbalised, and seemingly normal to each other.
