I've said it before and I'll say it again: Boy, do I love my bosses.
We have a program here where if you do something particularly useful for the company (or catch something that could have cost a lot of money/embarrassment), they'll announce it over the PA system, ending the announcement with "Thank you for a job well done."
I've only gotten one since I started (mostly because there's almost nothing here that's outside of my job description [which we don't have] and I'm supposed
to catch that stuff). The one I got was for recommending a small table be put in a certain location. Simple solution to a simple problem, but something that didn't occur to the rest of them.
