A woman goes into a adult toy shop to buy a dildo.
She sees one behind the counter and tells the salesman, “I want that one!” He replies, “It’s not for sale.”
The woman says, “Please I want that one,” again he says it’s not for sale.
The woman says, “I’ll give you a hundred pounds for it.” and the salesman says, “Well, okay.
Five minutes later, his boss walks in and asks, “How’s business today?”
The salesman replied, “It’s pretty slow but I just made a hundred pounds off of my thermos.”
