It is all in the economics
Gents, this is all about economics. Supply and demand applies and prices will go up or down depending on demand, traffic, availability, uniqueness, etc. The problem here is when a monger seems to have experienced a cock rolling so damned good they tell the world she is worth twice her going rates. Guess what? She will raise the rates, duh! That is not supply and demand, that is telling telling the shopkeeper "Hey dude charge me more for the sandwich, is too good to be this cheap". In the end the sucker ends up paying more, and cannot enjoy the sandwich as often, and screwed everybody else who does.
Now unless the pussy actually talks and sings and teaches cocks how to debate politicians, it is just another pussy. Simple. Don't go around telling the world is sooooo good it needs to be wrapped in gold foil and charged tenfold, or worse, tell the provider in private her rates are too low, and she should be charging more. This already happened to one of our recently retired UTRs and she went overboard with her rates.
So if you don't like to negotiate, or if you feel it is disrespectful, the by all means don't do it. Just don't overpay. GPS is real and if you walk away the prices will stay competitive, and reasonable. In the end, we set the prices, and we make the legends.
