We had a colleague going on mat leave last month and I have proposed to buy her a gift as a small, closer group (8 of us). I offered to sort the gift and pay in advance, shared all the options and agreed on a budget with everyone. Problem is that 2 of them haven’t yet paid me back and now I feel it’s been to long to say anything. I am not very comfortable asking for money but we ended up paying £15 so I am left £30 out of pocket for this. Is it pathetic to ask for the money back? I work in a high earning industry and my colleagues are all pretty well off so it isn’t a matter of them not having the money. Equally because of that, I feel a bit bad chasing people for it. What would you do?
