Think it is great to have a network such as this to warn each other and prevent others from having their time wasted.  But while it really is tempting to tell people that you caught them out as timewasters who called you before it might be wiser to swallow the urge and just instead not answer.  Some guys might be prompted to get another cheap SIM card and actually try and waste more of your time and that of others.  Better to contain the situation, store their number and let them keep ringing.  Or answer and tell them you are busy. 

You are sooooooo right BH but just couldnt stop self, was just in the right mood for him!!

LOL  I know and we all want to at times just tell them what for but it is actually more satisfying to ignore their calls or take a deep breath, smile, answer and sweetly tell them you are busy (till Saint Never Day)

good point...you never want to tip your hand. I had one person who didnt think I stored his number, but he caught me on my other phone once. Then he calls back on a Friday night, rings the phone once. Probably expecting me to jump up and call him back, and him not answer thinking I missed a booking.
