I agree with Supergato.
Yes, a true ho, as SG says will give a frequent customer a good service, extras, MAYBE a discount, and MAYBE for the same price more time.
But freebies for constant services? Naw!!!.
If a Ho gives a specific customer a freebie, she's lost that customer. The customer will never want to pay again.
Why would he if he got it once free?
That is the only scenario that aplies.
