I am aware that I am in a tiny minority here, but I hate, hate, hate it when I am addressed by my first name by cashiers, service people, etc. who don't know me, have never known me and will more than likely never see me again. My first name is for people I have personal relationships with. Period.
I am aware that their employers train them to use my name, so I don't blame them, but keep my name out of our one-time business relationship.
Thank you for listening. I feel better now.
