It certainly does Turtle, in my early punting days I had 2 experiences that led me to be more thorough, 1 good 1 bad.
First the bad, I rang an agency (one of the £100 per hour ones) and the girl who answered my door was absolutely stunning, very close to being the fittest prettiest girl Ive ever had the chance to fuck. Jason would rate her looks so complicatedly with different scales

but most of us would think Fuck yeah!! She came in said hi, i was a bit tipsy, and bent over in her tight mini skirt and said "you like?"damn right I did, she rubbered me up and bent over demanded a good seeing to, so I did. Now this all sounds great but heres the kicker, I was a bit pissed and didn't notice that she was there a sum total of 25 Mins, that was my fault but the next bit is where it all went down hill. We had a quick fag and chat, she asked if id be interested in meeting her for an overnight for £500.
I said yes exchanged numbers and next time in town made arrangements. She turned up looking a million dollars, so far so good, paid the cash and thought "well I'm 45 or so, there is no way I'm fucking for the next 8 Hrs or whatever" so lets go to the casino for a drink and a bit of fun. Well to cut a long story short this is where I found out that her English was pretty much " you like?" and "Fuck me!!" So back to the hotel for as much cock time as I could manage. We had great sex, after which she started to get dressed. I asked what on earth she was doing, you come I go was pretty much the whole discussion. This got heated at which point she took her clothes off bent over and said "fuck me then!!" bloody hell, what she was saying was if we weren't fucking she was going. Jesus, I told her to do one.
Well I've rambled a little bit so will tell you about the bait and switch who was great value later.
