Just to be clear, any remarks I personally made about over or underpaying aren't to single out or ridicule anyone, unless they are unreasonably cheap as I expect a minority of people here are. It's a free market and we all make decisions based on perceived value and what we can afford. But each provider isn't really "their own market". They know the "going rate" as well as we do based on what's on the menu, location, looks, cleanliness, personality etc. and charge whatever they think will be best for business. If I tip a girl an extra 20 it isn't a flex, it's just recognizing good service and I'll do that only when a provider is charging reasonable fees in the first place and it's someone I'll be seeing again. I don't believe in undertipping though unless service is bad. I'm not trying to dictate prices or force anyone else to overpay. Frankly I don't think a couple of extra bucks is gonna make much difference anyway.
Also, if someone can barely afford this expensive hobby, no hate but maybe their priorities are off and they should just go get the Jergens. For me, I am dumbstruck by mongers that routinely spend $$$-$$$$ and up week after week. Good for them but Its not an option for me, so I go for more affordable choices, like a rational person would. When I was really broke a few years back, I almost totally gave the hobby up, except for very basic services on rare occasions. But it wouldn't occur to me to try and waste a working girls time by shortchanging her. To me that's just as bad as a sketch provider that shorts on time or service. If I can't pay the going rate I do without.
