This is part of his message:
'I am in London next week with a friend - 27th and 28th. Would you be available for dinner i wonder? Staying at (hotel name)... next week's trip with my friend Steve is all about good food, drink, shopping and fun...so if you can handle that - would love to hear from you!'
"If you can handle that"?
"next week's trip... is all about... fun"?
He sounds like a fantasist and a loser. I expect that if you meet up with him and, er, Steve, you'll just end up being pressured by two idiots to go and shag them both for free. Or in exchange for a couple of drinks, if you're lucky.
This thread reminds me of why escorting is approx 1000 times better than sugar-daddy-seeking; you can dismiss all these ridiculous idiots and go straight for the, "Hello, my name is Bob and here is ?200 for you" lovely clients.
Don't forget the warnings that have been posted on this very site about creeps and abusers who use sugar daddy sites to find a huge pool of women who are clearly a bit desperate for quick'n'easy cash but who are, for whatever reason, not going properly pro (with associated set rates + security measures). I've heard stories of men renting flash cars to "take [you] out on a big night on the town" only to end up pressurising the woman into sex (in a cheap hotel) and getting the hell out of there when she starts asking for that ?1000 he mentioned earlier. They give fake names and addresses and probably enjoy themselves royally, messing women around and paying nothing for it.
It's not that I don't think a wise woman can't use a sugar daddy to get a lot of good things. But... if there were 100,000 wealthy chaps waiting out there to pepper us with ?50 notes, don't you think we'd all have a couple of them on hand?
It's much more common that even a full-time working girl will only have one super-generous and rich client at a time; even full-time sugar babies rarely find it possible to maintain a continuous and beneficial relationship with a rich man without both parties wondering if they're getting screwed over.
I recommend waiting til you get a better response from the sites, from someone who sounds sane, serious and sensible, and then take it from there. Probably don't meet anyone who's bringing along his mate Steve.
