Bro... you hit the right bottom!! That is SO fucking true!! More expensive DOES NOT mean better service at all just like in TO... $150 cad might be even better than $250 for a full hour.... it really depends on the gal and how "connected" you are with her!! Sometime I think more expensive or great looking does not mean she will provide the best service!!
Bottom line is be nice with repect to all those gals and u're get the best service for your $$
Cheers!
