Rip off agencies are those that prey on unwary men.

Making a booking with Chic is really simple. However, there are some things you need to know. Once you have chosen the girl you wish to date, call the 24/7 phone line to make a booking. At this point you will be given an all inclusive fee that has no hidden costs. Included in this price will be the London escort’s travel expenses; she will arrive in a chauffeur driven car to your chosen destination. Bookings are an hour minimum; travel costs are included in the first hour, and any subsequent hours will cost just £110.
Note that the price quoted £110 is for the second
hour. It is featured so prominently as to lure men before they're hit by the true cost by which time the Agency hopes they'll be thinking with their dick and will agree to any price.
Note the reference to "chauffeur driven car" implying the girl will be delivered in a limousine - in reality it'll be a girl, or even two or three, who'll be driven round in the back of the car from one man to another - without any chance to wash or shower after seeing each man, so that by the end of the night the girls will be exhausted, hungry and bodily filthy.http://www.chic-londonescorts.co.uk/rates-and-services/
