I guess it's always good to stick to the rules, especially with zero FB:
1. Always make a point of talking to the girl on the phone - try to find out a little about her as this will help determine if you're talking to the girl or an agency!
2. When you arrive do the spot checks.
Does the house look ok, tidy and in a reasonable area?
If ok, knock, but before parting with any money, do below by the front door NOT in the bedroom, and be prepared for a quick getaway!
2a. Does this girl sound like the one on the phone?
2b. Does she look like the girl in her pictures?
2c. If full GFE was promised, try for a DFK to test the water!
If worried about any of the above, (a, b, or c) and you feel a getaway is necessary, while still at the front door, start coughing violently and ask for a drink. When she disappears to get one....... leg it!!!
2d. Before being led into the bedroom, use the loo to see how clean it is (good place to do this check)
These checks can tell us much before we part with any money and we're still fully clothed ready for a quick exit!
