Or most of my shopping really. I know it's unreasonable for me to be annoyed, because I could just say 'no thanks, I don't need it' but they don't usually ask, and sometimes call you back for your receipt and then I act grateful! Like I'm going to need to prove I bought that booze instant coffee and toilet roll. Yes some people claim things back for tax, but even when I do that, I use my bank statements because I've paid by card. Yes you need a receipt for things you might want to return, but that's not a muffin generally. Anyway, AIBU to wish shops would just say 'Do you need this receipt?' instead of just handing me it?
