Dated the assistant manager of a Kay Jewelers where I worked during college. She was 4-5 years my senior and had dropped out of college after a year. Very attractive though; I enjoyed watching guys ogle her when she sold jewelry to them and their sig others. She was actually in a long term relationship in which she was very unhappy (they lived about 45 minutes outside of town...she had a long commute).
An all together awkward and fulfilling experience. I definitely got preferential treatment. After about 5 months, it informally ended when she got transferred to her own store; I think we both knew it wasn't going much of anywhere.
Everyone (but the manager) in the store knew that we were involved (the manager wasn't the brightest bulb in the box...she thought that the verb of "documentation" was "documentate"). I think part of the manager's ignorance was the age difference. I think an even bigger part of it was that I was clearly a nerd who loved talking about economics and history and studied during the slower hours and the AM was sort of a stereotypical blonde. In my manager's mind, there was no way that was ever happening--zero overlapping interests. The AM was also a bit white trash in an endearing sort of way.
Everyone around our store knew as well (we were in a strip mall, so generally everyone went to the same restaurants).
As someone said earlier, it's a bad idea if you want to stay in the company. But if you are young and it's a part time job, absolutely go for it. Just don't go to hard (I imagine it'd make things really awkward if you swing for the bleachers and miss).
