They only seem to use it when I have asked them to change/fix something that I'm not happy with and they are trying to 'explain' to me why they shouldn't change/fix it or why it doesn't need to be changed/fixed. I did actually ask one not to call me that this morning and said that I thought it was patronising and he said it wasn't meant that way, it's just the way he talks but he doesn't use it on any other occasion! So AIBU or is just a thing that some people do?
