Dude not cool to be shitting on the customers of any spa. Pick me sounds like a fake account with all the quick short posts as if this is a chatroom. If you take an issue with Pick Me, don't bring othees into it.
I can't comment on hygiene habits of other customers but if you are on the safer side like me you can ask for the sheet to be changed right there at the start of session and if it's important for you, you can ask a girl to take a shower. Personally I don't know how strictly any of the spas follow a protocol of girls showering after every session, considering how busy places get, I never assume an attendant is freshly showered on my session.
I don't think there's anything wrong with having 30's or 40's attendents with an occasional younger attendent mixed in. Not everyone is obsessed with 20 year olds with genz attitudes but if younger girls are the focus, I think holistic places may cater to that need better.
I agree my experience here was dependent on the girl. Some were more tip hungry and had a little attitude, some were service oriented and were smarter in understanding they can make more money if they don't nickle and dime you and instead have you as a regular customer
