Well here is a true case of no social site/ dating site involved, and may well be a heads up for some, I hope.
A guy I knew who was single in his late 30s, and a nice social, upstanding man. He like many others his age went out to bars and clubs to enjoy and hopefully meet a female partner.
He did one night spent 2/3 hours chatting and having a drink ( he doesn't drink alcohol ) never has, only soft drinks, they arranged to meet at the same bar 3 nights later, they did and had another 2/3 hours chatting and being sociable. At the end of the evening she asked him if he could give her a lift home just 10mins away, he did
the address she gave him, and showed him the way was bogus, he dropped her off in a dark carpark near the so called address, that she requested, when he stopped the car for her to get out, he was attacked, beaten, robbed by two males, they took his debit card, forced the number out of him, and drained his bank account. Needless to say he never saw that women again anywhere since, in or out the bar it was all one big set up. So take care!!
