The garage mince pies story sounds … rather daft! I think it was a well-intentioned plan, but not not ideal. Anyone, like you, buying the pies for themselves then looks rather uncharitable. The solution could be to purchase two boxes, one for yourself, one for the hospital. This could be the latest equivalent of BOGOF - now BTGOF, Buy Two Give One Free. It doesn't have quite the same ring to it.

Good to know you're well-acquainted with Nando's - someone has to be! No, it's a perfectly fine food place. I decided to stop calling it a restaurant when I discovered the logistics of eating there - sit down, peruse the menu, go to counter to order and pay... A little later, food arrives at the table and I have to get up again, to add my chosen selection of condiments, spicy sauces etc.
