The size of superstores

Reading the comments of late, there is a side issue developing on the sizes of the stores. In order to give people a reference to work around, here is the story so far...**

Population - approx 7000
Tesco store - approx 40000 sq ft
Sainsburys - approx 25000 sq ft

OK, these are just numbers, a completely off the wall comparision (and to prove that SU4S is watching all supermarkets) let's go to Crewkerne.

Crewkerne has a similar size of population, and guess what? Yep it's having a supermarket, this one is Waitrose and it's projected as a 19300 sq ft one.
As far as I know, Waitrose doesn't do white goods (yes there is a a small John Lewis bit in the Sidmouth store) so it would be a reasonable assumption that Tesco propose to do white goods or similar, whereas Sainsburys may not be able to fit them in. Please discuss in the comments section, that's what it's there for.

**happy to be corrected on these numbers
