I wouldn't necessarily say me and my coworkers are friends, but we are friendly. We do small favours for each other and we're always saying thank you. It's something as small as holding open the door or moving a cup away from the edge of the counter for them so it isn't knocked over.
I don't know my coworkers very well. There's one or two that I chat with often. I know they have a Subaru but they love Mustangs, they have an allergy, that one cup that is always in the back is theirs.
We just like each other. We aren't friends but we don't have to be. Sometimes a coworker makes me a drink or I get them some ice cream during downtime.
I also have a few coworkers that I'm less drawn to. But I don't stop being helpful. I'll still cover for them when they go to the bathroom.
I guess what I'm saying is I don't understand people who say they can't stand any of their coworkers. Of course there are places with people who are having a bad time and people that will never be nice.
But sometimes I wonder if they just haven't talked. Even small talk (yes even if you hate small talk) about their morning or how their dog is doing is all it takes. You don't have to be friends. You just have to ask if they're okay if you hear a crash or they say "ow'.
Me and my coworkers say goodnight to each other at the end of every shift (except Sundays, which are morning shifts). We just say goodbye and wish them well. Why do I have to be best friends to care about you?
Anyway this is my rant about people being inconsiderate to strangers/acquaintances. I've overheard this kind of stuff a lot recently when out and about.
