Wee..eeeeellll.... Let's discuss it then
Providers should treat every gentleman as a potential regular (just in case he decides to become one). However, in reality, being a "regular" isn't the name of the game. Variety rules in the hobby. We can't rely on regulars because life happens (they move away, the SO discovers whats going on, etc) also we can't depend on how regular a regular is (once a week, once a month, once a year?) I have a few guys who SAY that they just see me and one other gal on a regular basis, but his regular basis is generally once a month - maybe twice - maybe once every two months.
So yes, it would be nice to have five regulars who all see me at least once a week. In the real world, we know we need to keep new clients coming in because regulars typically do have a shelf life for various reasons, not all of which may have to do with us and how well we treat them.
Discounted multi-hour sessions I do reserve for "regulars" but I don't advertise them. That's something I prefer to discuss with them. Personally, and don't frown on me due to this please, I only want a new client for an hour until I can determine whether or not I can stand them for longer. I don't want a new client booking me for two to three hours and come to find out we don't "click" or they annoy the hell out of me. I may be able to put up with them (and honestly vice versa, they may not like me) for an hour at a time but I'm not that great an actress that I can pretend to like them for more than an hour. Hence only schedule an hour with me and we will see how it goes.
