Not a substitution but we once received 20 X 4 packs of pots of hummus when we don’t have that at all. It had arrived bagged, as in a collection of bags was dumped on the kitchen floor, so we did not notice until the driver had left.
I frantically checked that we had not ordered in error, but no, no mention of hummus on our order. I called and was told to keep it.
Not sure what one earth we were supposed to do with it, most went in the bin as the fridge was not big enough. I pity the poor person who was so desperately in need of hummus, must have been having a party, and when their delivery arrived…. no hummus!
On a brighter note we also once had a bottle of wine unexpectedly dumped on the kitchen floor. We were told to keep that too 🙂
