I get it if it’s at a place like Starbucks when you verbally say it. Everyone has a special way of spelling their name and you can’t know the spelling based on how it was said.
But when my name is literally written out in the previous email and you are replying to that email…bruh.
Makes me want to passive aggressively write theirs incorrectly too.
When I worked in support, I’d always have folks convert my last name into a similar sounding first name… ignoring my very present actual first name.
