Look vendor from work, salesperson, bill collector, even co-worker.
I realize that my name is a little out of the ordinary. No, really I do, I've lived with it for 33 years and have yet to meet face-to-face a person that shares my name. I've gotten used to the mispronunciations and I'm okay with that. I can let that pass.
Please, please, please, if I leave you a voicemail in which I clearly spell out my name for you and repeat it twice, which I always do, please be kind enough to spell my name correctly when you contact me. And if I email you? How much effort does it really take to perhaps cut and paste or click ignore when your email gets spell checked?
Hey Bob, Sue, Bill and Mary, I spell your name right. Take a minute to get mine right when I've handed you all the tools to do so.
Sorry, that's my rant.
