I want to know the answer to the following question:
What sort of customers did Selfridges most often cater to?
All the background I'm provided with is that "Selfridge attracted shoppers with educational and scientific exhibits; – in 1909, Louis Blériot's monoplane was exhibited at Selfridges (Blériot was the first to fly over the English Channel), and the first public demonstration of television by John Logie Baird took place in the department store in 1925.". Is that enough to answer the question?
