Back to the subject.
I would guess that in most cases, the lady is not exactly the same as advertised whether the ad be in the classifieds, private, parlour, web etc.
Age is probably the first exaggeration then dress size, looks etc.
If a lady turned up to my door and was absolutely not to my liking to the point of cancellation, I would probably honour a $50 cancellation fee to cover the lady's travel time & costs.
Bear in mind I did state 'in most cases' so therefore there are truthful gems out there to behold.
