As much as I think that the parents should have thought the name over a bit more before putting it down on the birth certificate...but at the same time, it's none of the store's business what a couple names their child. I'm sure the store as a whole couldn't give a crap. It had to be the deli/bakery workers that refused it. Personally, it's their job. If someone wants Happy Birthday JackA** on a cake, they'd do it. If they wanted Happy Birthday F***er...it's the baker's job to do it and even ask how to spell it to make sure they get it right.
So what if the kid's name was Adolf Hitler. A few baker people and the family would of been the only ones that saw it. It's not like they have to go over the intercom and yell, "Adolf Hitler's birthday cake is ready!"
I don't see what the big deal is. I grew up with someone named Adolf. It's a nice name. I do think that the parents should of picked a better pairing of names, but the kid can change it when he's old enough. *shrugs*
Just my opinion.
