They've obviously got the floor-planning of that store worked out well, Clover!
At Morrison's in Ipswich (which is the only supermarket where I feel safe enough to shop at the moment, unless I take a long drive to Waitrose on the far side of town) the queue for the tills is routed as a zig-zag path through the 'Nutmeg' range of children's clothing, with nobody rushing to make any impulse purchases there!
I'm generally quite good at resisting impulse purchases anyway, although I do have to hold myself back sometimes in the magazine sections of supermarkets.
