An accountant was at a convention in Las Vegas and decided to check out the local brothels. When he got to the first one, he asked the madam, "Is this a union house?" "No, I'm sorry, it isn't." "Well, if I pay you $100, what cut do the girls get?" "The house gets $80 and the girls get $20." Mightily offended at such unfair dealings, the man stomped off down the street in search of a more equitable shop. His search continued until finally he reached a brothel where the madam said, "Why yes, this is a union house." "And if I pay you $100, what cut do the girls get?" "The girls get $80 and the house gets $20." "That's more like it!" the man said. He looked around the room and pointed to a stunningly attractive redhead. "I'd like her for the night." "I'm sure you would, sir," said the madam, gesturing to a 70-year-old woman in the corner, "but Ethel here has seniority."
