I do 4 hands all the time and the norm is double house. However in places where I am a known quantity and I show up at night when it’s slow, I have a standing deal where I pay 1 house, get 2 girls, pay both tips, and if another customer comes while my massage is happening and a girl is needed, one of my girls handles him, and I prorate the tip. It’s win/win. I’m tipping a girl who would otherwise be sitting around idle, and I get a deal on my house.
