You have to be prepared when you decide to do your grocery shopping late on Sunday. Along about 3PM, all the clerks are exhausted from the weekend hordes. They become glassy-eyed and their work takes on a don't-give-a-darn air. When you get home, you find your groceries seem to have been packed by something using less than normal human reasoning.
For instance, I got home today to find one sack contained my ice cream - and the dog's Milk Bones. Another sack had my canned goods - and an avocado. One large sack held only a small package of coffee - while another sack was crammed to the gills with what should have been 2-3 sacks worth of fresh fruits and vegetables. Less the cantaloupe which had escaped whatever sack it was originally put in and was rolling around merrily on the floor of the car.
I try to be relatively calm when I've put off my trip to the grocery store until late on Sunday afternoon. Those people are shell-shocked and can't really be held responsible for their actions.
I wonder if you can iron bread.
