This one was memorable.
I used to work for a big company - a very large and roundly hated cable provider. They were incredibly cheap, and pinched pennies in every way imaginable. One year they celebrated the anniversary of their founding with a mandatory company picnic. If we didn't attend, we'd be written up. No time off granted, so it came out of our PTO. So on a dismal Friday afternoon, we bundled off to the "big party."
Which our asshole boss - the king of asshole bosses, he made the UK "Office" seem like the US "Office" - had scheduled for a park. Lo and behold, that park was directly across from his house. And this "park" was a patch of grass next to a huge highway overpass. It started raining, but the "party" was not rescheduled, we were all told to attend. It was held under the overpass, with all the bums in their tent city. Who, by the way, ate better than us because we were each allotted either one burger or one hotdog. They were frozen burgers and dogs from the local supermarket. No alcohol permitted.
The "highlight" of the "party" was a raffle drawing for what we'd been told were going to be really great prizes. This at least wasn't too improbable, since vendors from big companies would send us extravagant gifts to try and persuade us to buy their stuff. It turned out that the big prize was, in fact, pretty cool - an R/C car that was one of the ones that was like, gas-powered and pretty expensive and all that jazz. Everything else were little grab-bags full of company branded tchotchkes or t-shirts or whatever.
Naturally the asshole boss drew his own number - total coincidence, he promised! - for the big prize, which he took. There were exactly enough grab-bags for everyone there, except one. Naturally I was the only person who didn't get one. Mind you, I didn't care to have a company-branded t-shirt, but it was the fucking parsimonious, cheap-ass attitude that went with it that pissed me off. That, and the asshole boss walking over, pointing and laughing at me whole-heartedly and brushing tears from his eyes, saying, "Sucks to be you!"
I seriously exercised some willpower, and just didn't say anything, and made to leave. He yelled after me, "You haven't been dismissed yet, you have to stay until 5!" And then pointed and laughed at me some more.
Yeah, that was the worst party I ever went to.
