Lock Story 1: Bank Holiday Locksmith
Elderly neighbour locked herself out, distressed at the cost of a bank holiday locksmith (but not quite distressed enough for the police to break in for her) she mentioned there were keys inside in the lock of the other door.
Out we went with toolbox and a small mirror to make something to hook the keys out through the front door letterbox. Took maybe an hour, Victorian terrace street plenty of people passing and not one single person queried or even jokingly mentioned what we were doing.
I guess it was the toolbox. I'm told a hi-viz and a bucket of water will get you in just about anywhere.
