Just ask where he's driving from, or could he be staying in a hotel ?? I always ask on phone so where are you driving from and I also say if it's near me , is that work or home, one guy said same town as me ( it's small) so I just said "sorry I hope you don't mind I'll decline " they just said " oh no , of course that's fine" they knew what I was getting at and at the time taking Incalls from another town but the place he was coming from was where I lived ? I had one guy guess where I was and kept calling me on his lunch break trying to make a booking I could see him out of my window ( he had no idea of the road just the estate ) but I guessed it was him so said goodbye and watched him put phone back in his pocket.......it's a cut through so lots people walk past, plus I haven't any face pics etc....but I'd prob decline I always think it's a guy I might know trying to find me out , that's why I like talking on the phone .....and most of the guys I see DONT want to see someone in their own town , in case you 'out' them you could be a nutter too !!!
