Just popped to Screwfix to pick up my online order. The order had kindly been picked and bagged up. I was halfway out of the door before the guy realised he had to charge me for the bag. He insisted I could take the bag if I paid 5p and seemed unhappy when I refused and insisted on emptying the bag and carrying the four items out by hand!
He pretty much destroyed the bag getting it open and ripping off the invoice which was stapled on. I doubt very much the bag will get reused which is a shame.
