One L. Two Ss. It's really not that f***ing difficult.
This happens to me too often for it to be a typo or bad luck, and it's usually the same people over and over again. People just don't give a crap how they spell my [real] name. I think that's rude. It's especially annoying to see my name incorrectly spelled when 2 lines above the body of the email, in the To box, the email server has correctly resolved my name and displays it. Hey, shit-for-brains, look up! See that name? Yeah, that's how you spell it!!!
I have enough trouble with my last name as it is. Having my first name misspelled just adds to it. GRRRRRRRRRR!!!!!!!
Seriously though, how do you handle these people who don't seem to give a crap? I want to, but can't, be unprofessional about it at work. I am, however, incredibly sick & tired of seeing my first name get mangled. I've come to expect it with my last name, but come on -- my first name is not difficult, and the company address book can tell you how to correctly spell it. Any suggestions?
