The union maid
A dedicated Longshoremen's Union worker was attending 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," she replied, "I'm sorry, it isn't."
"Well, if I pay you $100.00, what cut do the girls get?" he asked.
She replied, "The house gets $80.00 and the girls get $20.00."
Mightily offended at such unfair dealings, the man stomped off down the street in search of a more equitable, hopefully unionized shop.
His search continued until finally he reached a brothel where the Madam responded, "Why, yes, sir, this IS a Union House."
The man asked, "And if I pay you $100.00, what cut do the girls get?"
"The girls get $80.00 and the house gets $20.00." she replied.
"That's more like it!!!" the Teamster said. He handed the Madam $100.00, looked around the room and pointed to a stunningly attractive blonde. "I'd like her for the night."
"I'm sure you would, sir," said the Madam. Then, pointing to an 85 year-old woman in the corner, "but Ethel here has seniority."
