Some think that a mere 20 minutes in the bathroom for a good scrub and groom and sampling of their toiletries (not forgetting pervy stuff with heated towel rails) and then coming out and declaring the 30 minute appointment starts from now, well I suppose some of them have a point. It's a bit like going into Tesco for a buy-one-get-one free and saying I'll just have the free one for now thanks.
There is a very posh brothel in Rio ("4x4") and it costs very little (about a fiver), or nothing (depending on time of day) to go in, enjoy the bar, showers, saunas, air-conditioning and locker room but if you take a girl the prices start at something (to my mind) outrageously expensive.
But it is only down the road from knock-shops with limited shower facilities. Time starts from when she grabs your money (usually a few minutes after she grabs your dick and you say "sim, ok." Price for the shag: depending on currency exchange rates, less than a fiver if you're quick.
Guess where I go for a long shower.
