Going off on a tangent (as I usualy do)......
I was called out to a "no supply" at Mitchel Shackleton in Eccles, but on arrival could not find anyone (the factory had shut down years ago), so wandered round trying to find the substation. I found myself in a long bay (1/4 mile long?) with all the machienery removed but all the old notices up on the wall. I noticed the floor was made from small blocks of wood 3x2" set into the floor end grain upward and realized that the whole bay had this "woodwork" whose sole purpose seemed to be to provide a non slip surface for all the clog wearing workforce.
Being the only person I am aware of who wears clogs to work it realy hit me that the chances of seeing another pair of clogs on this floor again were zero!
The effect is replicated in Boltons indoor market (albeit in concrete).... progress eh!
