To be fair, any job will do that to a person. I worked in a whisky bar for 5+ years with decent pay and loved most of it, had a lot of fun. Worked my way from a casual bartender to fill time salaried venue manager. Won international whisky and cocktail awards.
But it started to wear on me having the exact same problems with the owner of the bar every single week, and the exact same conversation with the exact same regulars every single day. The only thing that changed was the people I work with. I started to feel like I barely knew anyone anymore because most of the staff were students or backpackers so they were in and out in 6 months tops. After the last full time bartender left for a different career it felt like I lost my last friend.
One day I rocked up to work to start setting up and the smell of the place hit me as I opened the door and I just broke down crying behind the bar at 28 years old. Handed in my 4 weeks notice that day. The owner didn't even bother to see me before I left even though he'd only owned the bar for 6 months longer than I'd worked there for him. A year later the place couldn't find a good replacement and shut down entirely.
Work is just depressing. We weren't made for this. And late stage capitalism is making things even worse where people aren't paid enough and aren't even considered employees anymore.
