Thanks for the answer, Dharma, as far as taking a shower goes, sometimes you have to after a drive and the provider appreciates it, but it should not last more than 4-5 minutes, and the same time as a shower after activities. But, after the greeting, getting undressed, showering, and drying off before and then the showering, drying off and getting dressed after, leaves about 40-45 minutes of BCD time of the hour I paid for if I am lucky, given that the provider only will let me stay for an hour of real time. IMO, a provider should make allowances for the other necessary activities before and after BCD time. If he is late, that is his fault, even it it wasn't directly on him. If it is the provider's fault that the session does not start on time for whatever reason, she still needs to provide the full hour regardless of other appointments after that. If he does not want a shortened session or she cannot dedicate the extra time, reschedule.
I knew that there would not be much if any response from other providers were not going to answer, especially the FS providers because if their answer is the former, clients are going to want them to live up to what they say, if they answer the latter, they might stand to lose business knowing that guys will see her as a clockwatcher. So, the providers avoid the question and let a guy find out on his own that more times than naught, it is the latter answer.
