They should know how to

I was going to say, how hard is it to spell Noah

I thought the person taking the picture was supposed to be a customer saying they spelled his name wrong but in the receipt it says the cashier was Noha. I must've misunderstood?

The person who made the image is either trying to imply that they are a customer called Noah and that somehow, people spell his/her name wrong so they went to the restaurant Noah's hoping that the people there would spell it right but they still didn't or, the cashier's name is Noah and the restaurant can't even spell it's own name

A girl is named Noa in my class

And it means brain in mine! The wonders of languages!
