The word "tolerated" covers a wide range of situations.
To an extent we are all being tolerated in so far as this is a business arrangement and if you remove the cash incentive, you will see how far you get! So we are all being tolerated to a greater or lesser extent for the cash reward.... unless of course the lady tells you to keep your money in your pocket... that's a different story! (The stuff of legend!)
However, having said that, I would imagine that sometimes the lady enjoys being with her client if he is nice, clean, is not a nutter
and knows how to treat her, both as a person and as a lover.
I am sure that if you are a smelly, rude, rough and ignorant guy then yes you are being tolerated for the money..... end of.
