What personality trait enables someone to assume agreement before it is given?

A car salesman acts as if the customer has agreed to buy the car, saying, “I’ll get the contract written up.” A boyfriend suggests a second date at some restaurant without even asking her if she wants to go out with him again. Or a man acts as if the woman wants to make love to him, again, without her explicit agreement. It’s a sense of entitlement, I believe, and I wonder where it comes from.

Have you done something like that? What was the situation? What allowed you to give yourself permission to behave this way?

Have you ever been on the receiving end of such a presumption? Why do you think the person who ran the trip on you allowed themselves to do that without consulting you?
