Certainly nowhere near the worst job evar, but it's the worst one I've had:
Working graveyards at Chevron. Minimum wage. No hazard pay whatsoever. The doors were locked all night, yet I'd be constantly harassed by all kinds of people. It was the only place open 24/7, so I'd get the creepy people coming by at 3am that had just gotten booted out of the bars. Admittedly, though, one of my best customers (who I still talk to, more than three years after quitting) used to come by around 3am. He was always sober, and he had a beautiful deep green 'Cuda. Made me jealous.
Two seedy hotels were next door to the place, so I'd get a lot of visits from junkies and hookers. The transgendered hookers were always amusing, though. I'd get randoms coming by to hit on me, to just chat, to yell at me, to get me to call them an ambulance because they got their ass kicked, or to beg me to use my phone because the payphone wouldn't work.
I had to open the doors at about 6am. Presumably people from the Triple O's (fast food place attached to the station) would be around, so I wouldn't be alone...but that wasn't always the case. But you'd be surprised how irate commuters get when they don't get their daily coffee and newspaper. I often had people come by as early as 4am demanding coffee because they were going hunting. Bah. And the truckers... Most of them were evil, cranky bastards. It's not my fault you can't find the fucking PetroPass, and no matter how much you bitch at me, I still can't give you fuel for your rig. IT'S. NOT. POSSIBLE.
When gas prices got high in the summer, people would actively blame me for it. Cuz, you know, I HAVE THE POWER!!!!
The highlights of my shift (which was 10 hours - 11pm to 9am) were talking to my contact across town every two hours (we'd often spend those two hours chatting anyway), and the last two hours when I got to go outside and clean the grounds. Most relaxing two hours of the entire shift. Srsly. :)
My coworkers were a largely good bunch, though I didn't see much of any of them. The station also changed hands while I was there, and shit just went downhill from there. At one point, after the old owner retired and the new one took over, the other graveyard chick was doing next to nothing on her nights, thus leaving me with a huge mess to clean up. I'd get reprimanded for "not doing my job," and when I explained that I had to make up for what the other girl missed BEFORE I even began doing my own work, the owner didn't believe me. He continued to treat me like crap the rest of the time I was there. I got sick of it, and quit. On my last day, I was forced to train two newbies for dayshift, when I myself only had four shifts' experience doing days. I was kind enough to stay an extra hour to help the poor kids, but only because I felt sorry for them. The boss could go fuck himself. :P
In the end, the whole thing was a loss. I worked four days, then had four days off. But those four days off would be spent sleeping. So I had zero social life. It was stupid. :(
