I saw the cheddar cheese and onion creation across the aisle yesterday (PSA-LHR). It comes on sliced white which looked like a supermarket (Asda perhaps) bargain loaf. The bread would certainly never have been allowed to darken the doors at Waitrose.
The gentleman who had taken the 'Enjoy your menu!' box looked at it with regret, he opened it up exposing the full horror of the contents and put it back in the bag and suggested, as have others that the box looked more edible.
I had taken the precaution of spending €6 on a prosciutto and mozzarella sandwich before boarding and it was very tasty. The very cheerful crew both commented that I had made a very wise choice.
I still have the €6 receipt. I think I'll send it to Alex and ask for a reimbursement.
