Yes, a few years ago, I arrived at the house next door, which was answered by a very refined and not bad looking mature lady. The brain had already kicked in that this wasn't the girl I had spoken to on the phone, so when she asked me what I wanted, I said, hopefully."..the ad in the Free Trader" ( or whatever) to which she calmly responded..."oh you want the knocking shop next door". Unfazed,and without a plan B, I toddled off next door!!
