I got a bonus one year at my old job- I can't remember how much it was, certainly hundreds rather than thousands! I'd been sort-of-seconded into a project, while still doing my normal work; it was really nice to be rewarded for that, and I had no idea the college had the capacity to give bonuses, so it was a complete surprise.
I think the concept of getting a bonus every year just for doing what you've been recruited and paid to do anyway is a bit odd, really.
