Well I was at the local supermarket earlier on, and a (check out) girl working there, who I've chatted with quite a bit over the last year, decided to give me a staff discount on my grocery bill.
I only noticed this a few hours later when, just as I was about to throw the docket away, I saw the words "staff discount" emblazened on the docket. While having a rather jovial chat with her when I was at the check out, I had noticed her swiping a card of some sort through the scanner, but didn't think much of it at the time. It must have been her staff card.
It's not exactly the sort of thing that happens often. At least to me.
Should I sent her a "thank you" email or IM?
Alphamale, what would you do in this situation?
