While visiting Australia a few years back we discovered that Woolworths in South Africa is quite unlike Woolworths in other parts of the world. The South African Woolworths started off as a upmarket clothing store - not like the Woolworths food shop that non-South Africans know. Slowly over the years it's become more affordable, and today caters for middle to high income groups.
I mentioned that the store started off as a clothing store; they then later branched out into homeware. A number of years ago the company introduced a food department supplying carefully graded, high-quality foods. These days we even have petrol stations (service stations) with small on-site Woolworths convenience stores that are open 24 hours a day. They're awesome - and a great step up from the often-dodgy convenience stores found at many other petrol stations.
