I only just discovered TER recently. Before that, my only experiences were with providers out of the (gasp!) yellow-pages.  Provider would arrive, collect donation and then explain that it's standard operating procedure for them to immediately transfer the donation to their vehicle. I remember watching with my not-so-proverbial pants down while the provider walked out with my cash. Sometimes they came back to render companionship, other times they didn't. Is the immediate removal of cash to car truly standard practice?

You asked:
"Is the immediate removal of cash to car truly standard practice?"

Only for cash-n-dash rip-off providers.  No reputable agency or independent escort I've ever heard of works that way.

Word to the wise ... no more yellow pages. Read your daily TER new reviews and stick with the good reports.

It will greatly improve your enjoyment of the Hobby.

TOMC

weekly ad papers, and local gentlemen's entertainment newspapers, like the Bachelor Beat in Phoenix.  Yes, you CAN have satisfying experiences using these sources, but you can also risk having awful ones.  Trust me, the ladies you want to see aren't there.

Personally, and I know a bit broad brush, I would include in the list of sources to avoid, backpage.com and craigslist, unless the lady links a number of strong TER reviews.

Face it, TER is the key to successful hobbying.  If you haven't done so yet, buy a VIP membership!!!  It is money well spent, and will greatly improve your chances of encounter a lady that will 1) not rip you off, and 2) will want to see again and again.

As Jazz32 says, spend the $20 to get a VIP membership and save yourself a lot of heartache over "walking money."  Check reviews (read not just look at photos) and you will have a wonderful time with the lovely ladies here on TER.
