We are a small team at work, quite close and have a good laugh with each other (6 men and 4 women.)
One of the male colleagues (joined the same time as me, just over a year) will only ever make effort with one of the other men - ridiculous over the top effort. Everyone else he probably wouldn't bother to speak to - not in an arrogant way, more in an oblivious way.
One of the women left this week and I was asked to do a collection (we do this for everyone) and he refused to contribute anything to it. I bought a tiny cake today and before I had a chance to offer it out he'd come straight over to my desk and helped himself without asking or saying one word of thanks.
I just think if you can't be bothered to contribute to someones leaving, it's a little cheeky to help yourself to their cake.
We run little incentives every other week and someone will buy some chocolate or sweets, and whoever wins always share it out afterwards. This colleague got a large chocolate Easter egg and shoved it straight in his bag to take home.
I know I might get a few comments like we must not be a team of nice people - but we genuinely are. He is just grating on me, that he is very much a taker and never gives anything back.
