Even the BEST market is set up as a trap to frustrate and confuse the ordinary shopper.
Aisles are narrow, paths from front to back labyrinthine.
At every turn and catchpoint, a teetering cardboard display threatens to topple should you try to squeeze past the decoy slow shoppers that the grocery no doubt hires to make sure you spend at least an hour in the store. I enforce certain rules on myself. Just when I'm sure I can't eat another bite, I grab my list and coupons and head out the door. If it really is a special, there will be more of it in the regular place. I don't buy things when I'm mad.
