either you ran into an inexperienced provider or one who felt very secure to ask such questions about prevailing rates, just tell her in this town the provider pays the client; as to questions about your preference in sexual positions, that is not unusual as some "girls" only act as bottom and a very few only act as tops, most will shake their money makers in what ever direction you need it shaken, likewise girls on hormones may not always be able to get erect enough to give you a full penetration and therefor they feel more comfortable on the first date only promising what they know they can deliver....
