They presented it to me today, a certificate of recognition (which I'll probably frame, cheesy as it is) and a challenge coin with the loss prevention department's emblem on one side and the company logo on the other. I had to take a picture at the front of the store with my assistant store manager and my grocery manager. A bit embarrassing, but it feels good to be recognized for doing my job well.
On the whole, though, I think I prefer quiet recognition. A "good job" here, a raise there, maybe a boost in my promotability, haha.
