1. Why are the ladies toilets always up three flights of vertiginous stairs?
2. Why are the larger sized shoes, presumably worn by taller people, always on the lower shelves?
3. Why doesn't Boots provide periscope so that you can see what's on the bottom shelves - or a surfboard on wheels so that you can glide along and bottom feed?
4. Why do I have to put my eggs in the fridge when they are presumably ok on a shelf at the back of the supermarket?
