Reminded of that time I ordered a bunch of food from a frozen food discounter, they turned up for the delivery, went "the one thing was out of stock, would you like this other thing instead that I have a few boxes of in the van?"

And then when I said that I wasn't sure if I would like the flavour, they opened a box of it *then and there* so that I could sample it and decide, and took it back into their van and just refunded the money instead when I indicated that I didn't like it

This was the same frozen food discounter whose previous business model was "here's a bunch of dates, times and addresses at industrial parks where our truck will be, show up with cash and you will get one (1) box of miscellanous frozen food", to give you an idea of the kind of outfit that this was
