I often leave the cart with the Wifey who holds a bizarre fascination with looking at multiple brands of the same item. While she is in the state of an immobile, perplexed shopping coma, I go and pick up the next 25 items on the list in nanoseconds. I return and dump them in the cart. I then let her know when she makes her selection we are free to go to the checkout lane.
It never fails that she looks at me bewildered. She can’t believe that I could possibly have every other item on the list in the cart.
