Hi Sean
I got locked in and the guy said bang on the wall when you're done (he was next door).....well guess what I nearly knocked the friggin wall down but no response. On checking closer there was a tiny window out back, but not large enough of someone of my middle aged girth and lack of dexterity to crawl through, and a great big plate glass window at the front. As it was in Mississippi I figured if I broke that I'd either be locked up by the sherriff or shot by the store owner - neither appealed to me as I had left Mrs G on a beach a few miles away and taken the car Anyway after about an hour he must have heard my pitiful cries for "help" , either that or I knocked some plaster off his side of the wall. He was seriously miffed when I came out empty handed too....
