AIBU? Standing in a queue in Tesco with (home from uni) DD chatting to me. I was clutching a much anticipated bottle of Pimms, with accompanying lemonade, strawberries, mint etc... goodies going through when charmless checkoutee asks for age of said 21 year old DD and ID for her or she would not be able to sell me the Pimms. I calmly explained that I (substantially over 21) am buying said alcoholic beverage with my money and a) DD is only standing next to me b) its my money c) DD is over 21 and d) what on earth... the manager was called and I was allowed to purchase. AIBU to think that this is ridiculous - I understand that adults must not buy alcohol for underage children, but if you were - would it be Pimms, and would you have the "child" standing next to you?
