Southwest employee is a grade A beotch for making a public scene in person and on social media. Not the kid's fault that mommy gave her an unusual name. Probably should be fired and should consider a career that doesn't involve face to face interaction with the public in a retail type environment.
I sure as hell wouldn't name a kid Abcde, but unless you all want to legislate what names are acceptable which quite a few countries do, it not anyone's business other than the parents.

I might be in favor of such legislation. Its at least 1 step in the direction of requiring a certain level of responsibility in those who wish to bring a child into the world.
