My skin actually crawled

Why do people insist on chewing gum with their mouths open? It sounds disgusting, it looks horrible, like a cud chewing cow and it makes it really difficult to understand and to take them seriously.

Customer: GumSmack Where are your best sellers?
Me: Right here (under the large sign that says bestsellers)
Customer: GumSmack then something completely unintelligible.
Me: Pardon me?
Customer: GumSmack Twilight?
Me: Just over here.


Believe it or not this was not a 13 year old girl. This was a woman in her thirties AND her mother!!!!!
UGH. Disgusting.
