Yesterday I found £20 in the carpark at work (an office). I handed it in to a woman in HR and usually they send an email round asking if anyone has lost any cash and to speak to them if they have. This happens at least once a month. However, an email never went round. AIBU to contact HR and ask if the money was reunited or is it not my business now I handed it in? I am not accusing the woman of stealing it but I handed it in with the intention of reuniting the cash with the owner and it doesn't look like they've done anything about it.
