Wow... uumm... wow...
What do you say to someone like her. Clearly she has major anxiety issues and is super insecure. Its keys, you are right. Noone will know what lock they fit in without them being labeled. The worst part is, more than likely you are going to come across them someday in a pocket of your pocketbook or in a drawer or something and this all would have been for nothing (on her part).
I'm glad your other client stuck up for you!
Girl, next time don't answer the phone and try not to get that upset over her issues. She is not normal to behave like that over something so small so don't let it make you sick. Its not worth it
I'm so sorry about your day yesterday though... yuck!
