Yesterday I was helping run a fundraising event and we were serving ticket holders drinks and snacks on arrival. One of the volunteer helpers and I just didn't see eye to eye and after thanking everyone who helped she has responded with what is definitely a barbed comment reflecting how she felt about me! She was happy to help but was giving away free drinks to her mates, helping herself and definitely didn't like me asking her not to do that as we need to be sure we had enough for all ticket holders. She's someone I find I have nothing in common with which I'm sure doesn't help.
I'm reflecting on things and wondering if this something I can change or should I just accept we don't gel and her volunteering was so she could help herself?
