Had this happen last week. I make probably one of the lowest salaries in my company (one of the younger ones, newer ones, and non-computer programmer ones). But my frugality is well known (always bring lunch for example). Two colleagues were talking about buying a 1000$ plane ticket (one of them is French and wanted to go home to visit family this year), and I didn't hear the rest of the conversation but at some point they passed by my desk and said something along the lines of, "with your frugality, 1000$ for a plane ticket must not make much difference to you". I just replied, "1000$ is a lot of money no matter how much I have in the bank, I don't see why it would mean less to me than to you?"
