I agree. Its all supply and demand. Sometimes they let you walk if they know the next guy can easily pay the amount.
The other issue is the lack of information. A lot of places don't advertise, so its basically just this site and a few others to find AMPs. Only a small fraction of the AMPs will get exposure so everyone is going to the same places.
Most mongers don't understand that one monger may get full service for 80 because provider has a vibe with him, good body, gentle or he cums quckly.
Providers set the menu and prices based on the mongers appearance and anyone disputing that is in denial.
Yes, a provider wants dollars but even they have limits.
Any dude that works out , decent looking and good hygiene will have a blast in this hobby.
Many providers have told me many of the customers ugly, fat , dirty.
A monger enters an AMPS door looking good it can go a long way for him.
