Example....I go to a makeup counter and Cindy Lu helps me. I like Cindy Lu and a few months later I need some help picking out makeup....I call the counter and say "Does Cindy Lu still work there?" And they say yes. Harmful? Normal? In your situation it's a bit different of course but the end result is the same. They wanted to know if you worked there and you did. It's all in how you look at it.
