Stop in for a cup of coffee

Sooo... I own a computer store... random guy comes in (front of store is all computer parts/computers.. you can see my work area all the way to the back door.. all computers (other than my trickflows and pile of car parts i haven't taken home)
"I have a quick job for you, The filling came out of this tooth" and proceeds to try to show me inside his mouth.... "Sir, why are you telling me this", "you have the teeth sign out front and i need this fixed"
"Sir.. that's doors over... this is a computer store"
Oh.. and walks away....

Not a joke or anything.... actually just happened to me...
