Any of these shops (wooden shelf/drawer ladder general stores) remain existent ? in Australia or Britain.
Look at the sketch the last time i saw a shop such as that was very oddly in around 1999-2000 but as would expect it was in such a town as Cootamundra (remote area) , Most of those types of stores were gone around 1975, many because the owners as i saw up to 2000 AKA died on the job and it then closed after the two or three generation stint of anything from 50 - 120 years.
More than that, the customer himself was probably never actually officially educated or retarded but allowed to run their own affairs without help, they were banished to the retardation institutions around 1975 also.
