Depends entirely on the provider. If they are low, low volume and INDY, you have a better chance of it happening as they most likely would be cleaning up after your date anyway.
Agencies are trickier. The busier/higher volume ones usually don’t allow for enough time to let the girls clean up. But if the girL has nothing scheduled soon after you they usually let you if they’re cool. Also, longer dates will usually allow it or if you’re the last date of the day.
Most of my dates I ask about it be says it is an act of domination/submission which can be a major turnon. I once discussed it with a VERY popular/well reviewed lady who was traveling to My city. Beautiful, sophisticated, hit all the marks. We discussed it and she flat out told me it was not on the menu because of the hair/makeup issue (and this was someone earning 4 digits an hour for what I was looking for - basically a weeks pay after taxes for me). If I’m giving that sort of gift, you better believe that I’m going to “take you to the spa” if that’s what I want. But if you are a Lower to moderately priced provider and it isn’t available, I’m not going to get mad, especially if you are working with an agency - you don’t get to determine your schedule yourself.
