Jack Cohen knew about the importance of scaleability in 1929 when he opened the first ever Tesco store, in Burnt Oak near Harrow in NW London.
He'd be a tad disappointed at the counter sign on his Goodge St Tesco metro branch.
i dont think this is what he had in mind.
'This counter does not have scale'
Presumably this counter that has a fixed number of transactions it is capable of processing, which will never change.
'We are unable to take payment of any weighted items'
Not only that, it seems it can only process 'virtual' goods.
