Well if you are an Escort and you are new on this industry, you must be very careful.
Always request a landline telephone to the potential client and verify it.
If you are not able to get this for obvious reasons, then meet in a public place or a hotel that works with escorts.
You must choose the meeting place and hotel.
At the minimum feeling that something is not as expected leave!
Do not get inside the clients car, and of course never work in the streets.
No matter how much the client wants to pay, but always use protection to prevent deceases.
