Do not give until you have gotten. It is a rule that derives from the nature of the business. The market is over saturated with "providers"; I am amused that a provider suffers under the delusion that he is the " end all", and, thereby, he can run the market. The reality of the thing being that "escorting" is a buyer's market. If the provider demands a deposit, walk on as I assure you, there is something bigger and better just around the corner who will be more accommodating.
