I don't know about you but when I go shopping I'm really super particular about how I pack my trolley and my bags, like proper OCD about it! I let a charity backpacker pack my bags during my last shop and I had 2 broken eggs, a squashed crisp multipack an bread loaf that had literally been flattened! I didn't say anything but WIBU to insist on packing my own bags? Making sure breakables and squashables stay on top?
