I have not been to England recently, so things might have changed. So,
@Growan ; take an English pharmacy and make it 35-50 times larger. Fill it full of stuff, toothpaste and feminine products, then throw in about everything else you can think of. There is always one aisle full of whatever they sell at th next holiday and an aisle for things that have been seen on tv. Each one typically has about ten employees but they no longer work at the cash register as they are less trustworthy than most customers. About 10% of the store is pharmacy. The pharmacy workers and store workers are not allowed to speak and are sworn enemies.
Oh, the prices are somewhere between reasonable and ridiculous.
Overall, think of Dante's third level of hell.
So take about 1000 or two of them and scatter them around properties in most of the US. They are ruled by provincial overlords in both Deerfield, IL and some guy called Tim Hortons in the Arctic Circle. Recently they tried a tax dodge to avoid paying US taxes by reclassifying themselves as Canadians but the Canadians turned them down.
