Which supermarket in the UK makes a hopeless blunder with one of our Deliveroo orders. If it happens to you (from now onwards) provide screenshots of the app where the mistake and date when it happened are visible, with enough detail to verify that one of the blunders happened. First confirmation resolves to true, all others resolve to false. Valid blunders are:

• Item is removed when "substitute if unavailable" was selected.

• Item more than an hour late after the estimated time at "… is packing your order" stage starts.

Tesco's blunder of not being available on Deliveroo and having a dedicated app that's even more hopeless doesn't count.

I cannot remove an option that was in error, so I changed to "(reserved for later)" before anyone selected it.

If the supermarkets are unrealistically competent up until the end of the year I'll try and make this resolve to void (or whatever it's called) so everyone gets the mana they put in back.

I shall not resolve it myself with it happening to me until at least December.
