Like ive said - its murky is massage, you mention places that appear to be legit but well lets just say nothing is purely legit. if they think they can extract a few pounds and cut no heat then the masseuse will believe me. it happens.
You make it sound as though every masseuse will give extras just by handing over a few bucks. I don’t doubt there are providers who appear legit who may give more to certain clients and you might be lucky enough to be able to charm them, but you make it sound as if you just flash your wad and they do whatever you want. There has been at least one post recently about a guy being huckled by the polis for being inappropriate with a masseuse.
I have been to relax Glasgow, and have made this point before, this place is very legit, and even before you get your first massage, you have to go through a consultation, where your asked to read, there terms and conditions
There is a paragraph about, sexual services, and it states, anyone asking will have there massage will end there and then and no refunds, even if you have paid for a block booking, 5 massages @ £25 each
One of the girls doing my massage, we got talking, and I raised the subject, but made it clear, don't want to offend you, do you get guys asking for sexual favours, and it seems they do, and they don't waste time, they tell them, get dressed, and don't come back
They are a licenced venue, and if it was found they were doing happy ending, they might lose there licence
