5 More Things to Make Great gals say Good bye

1- Rude to waiters. It's a real significant "tell". If he shows a lack of respect for a working person, he probably dislikes pets and children too. Besides you never mess with someone who feeds you.
2- Very nervous. Jumpy, has schpilkus (ants in his pants), taps silverware on table as if he's a drummer, makes little or no eye contact. If you see something worthwhile in him, try a second date. Maybe he just has a case of the first date nerves. Not condusive for attraction and romance.
3- El Cheapo. Either offers to split the bill. He says, "I have a rule that first dates are dutch treat". Or claims he left his wallet at home. "Hon, pick this one up, I'll get the next one."
4- Mr. Braggart. Talks continuously about himself; who he knows, where he's been and what he has. People who have to brag are a personality type that need to overcome their inherent insecurities by stroking their own egos.
5- Salesman. Makes you feel like you're being sold something. It's more like a business meeting than a date. This guy won't change, he is a salesman and probably will always be hustling you.
