Did anyone see tonight's Turn Back Time programme on BBC1?
I think you can watch some previous episodes through the above link.
The basic premise of the series is that current shopkeepers (butchers, bakers, grocers etc.) "turn back time" and set up store in a number of different eras to see how their business skills etc. would fare.
Tonight's episode was going back to WW2 but there have been episodes set in the 30s, Edwardian times etc.
