Free advice from a veteran monger
The mistakes that I have made over the years.
1) you went to her spot not yours. This allows her to get comfortable with ripping you off, since she knows the area and you don't. I. E she can run away or maybe her pimp or junkie friend is there waiting to give her a lift. So rule number one always go to your spot, you will know its a good one by how much she complains it isn't.
2) really don't need a LEO check once she gets in the car. I always grab her tit and make her grab my cock, but I don't do it to check if she is a cop I do it for the free feel. No cop and I mean no cop is going to get in your car. The way 99 percent of those stings work is they ask you what you want while they are out of the car and standing on the side walk leaning in your window that you rolled down. Then they tell you to go behind the building and they will meet you there. So rule number two just ask them if they "want a ride" and let them get in if she is a hooker you won't get to the first set of lights before she's telling you what is on the menu. If its a cop she has to "kinda wait for you to ask what is on the menu" so basically if you go two blocks and she doesn't ask you if you if "you want your cock sucked for twenty bucks" let her out. But never yell out the window while the hooker is standing on the sidewalk "hey how much for a Blow Job". If she doesn't just hop in your car when you ask her if she wants a ride there is a good chance she is a cop. And you just drive away.
3) The next mistake was not to as I say "hooker proof your car and self"this means putting any thing that is not fucking tied down in your trunk. They will steal anything Phones, wallets groceries you name it. I once picked up a BSW who had just ripped off the Rite Aid she had shampoo, ankle braces, candy bars and chap stick. The funny thing was when she got out of my truck she wanted some change for the bus and left all her stolen shit in my car. Hooker proof you car put every thing in your trunk. On a side note don't just have twenties these girls don't make change. If you only have twenties that blow job or F. S. Is only going to be priced like the ATM says in "multiples of twenty"
4) The last is going back to their place, its alright as long as they live there. But usually what they call their place is either their pimps house, their drug dealers house or a loose friend of theirs where they can go in the front door and out the back. So how do you know if they live there you don't. As you can see rule one and rule four are cousins to each other.
Don't feel bad and I hope you got a good laugh out of this advice. God knows it cost me money to learn most of these things. Be heads up.
P. S. If she is sucking your dick and tells you "you can't finger her because she's on the rag" its a dude. Learned that one first hand in the old combat zone.
