I certainly agree with comments posted in this thread.
(1. Provide the agreed donation up front and 2. don't expect a "Rebate", Ha!)
However, the
Glaring Discrepancy between the Opinions of the Providers and Hobbyists in these two correlated polls highlights a source of confusion and potential conflict:
Providers Opinion Poll: When do you expect to receive your "Donation"?
Hobbyists Opinion Poll: When do you expect to provide your "Donation"?
As Emily Post advises; in any business, sport or social grace, knowing the proper etiquette and protocol smooths the interaction for all parties.
PS: In My Opinion there may exist two rare exceptions:
1) If the provider you meet has
blatantly misrepresented herself in appearance or is an obvious "bait and switch",
I feel the Hobbyist may cancel the appointment is under
No Obligation to provide compensation for transportation, accommodations, or time.
2) If the provider is legitimate, but there is no intimate connection
Before the session starts, fairness would dictate the Hobbyist provide some compensation for cancelling that appointment.
PSS:
I have often read of the inherent unfairness of the following scenario:
Hobbyist negotiates a longer session,
completes his Primary Mission Prematurely,
Provider, pops up, dresses, scoops the donation and bolts.
Etiquette for time and money cuts both ways.
