Brother netnoy,
First, thanks for taking on the "Can they come back challenge!" I'm inferring you spent about $2k (allowance + expenses) and the better part of a week (spread out over time) to cycle through these reincarnations of POT's and SB's.
The test at the heart of the issue: can someone change over time? Looks like in these cases, the answer is "no" - if the individual is not willing to change.
As I experienced lately, a drunk SB is a problem to be avoided at all costs. There is too much potential fallout from trying to "manage" a drunk girl in public or private: Embarrassment, entanglement with hotel/bar/venue security, barf on your stuff, in your hotel room/home, or in your car, lousy or no sex (because she passed out), broken or stained furniture (I now have a wine spill-shaped stain on my living room area rug), etc.
Side issue: I trust we all realize that once your SB is seriously drunk, she can no longer give consent. There's a similar issue (but thankfully not as prevalent) with drugs (including weed when taken too much/often). I'll guess we have all booked a pro at some time who was flying on something when we showed up. And I'll guess none of us ever booked with her again.
The Sugar model, at its core, is predicated on the concept of mutual consent and transparency. We never want to fool or trick a woman into sex or coerce her using false pretenses. Booze and drugs clearly interfere with the ability to grant or even ask for consent.
And then there's GPS inflation. Once you got the "worth" statement, you lost. Full stop. I don't know if you could have discussed your allowance expectations before agreeing to meet. It looks like you did with at least one. Sadly, the GPS lives on, perhaps fueled by social media and so-called "Sugar Baby Influences" who we know are full of shit. Credit to you for not giving in to the GPS pressure out of expediency or "proximity induced lust" (i.e.: You used the big head to decide.)
Appreciate that you shared these with us. It's easy to share the wins. But sharing the mishaps and failures is important as well.
Life is good
