"I'm Sorry, We're Out of Bread — Here's an Octopus Instead"
Apparently, a potential hazard of ordering your groceries online is that, in lieu of walnut bread, they might send you an octopus.
Such was the case for John Goodger, who made use of UK chain Tesco’s online grocery ordering. The store was out of the walnut bread Goodger asked for, and apparently Tesco will substitute a similar product if they’re out of something you wanted. In this case, the “similar” product was a whole loose octopus.
