A standard notice from the Instacart home-delivery service about a grocery order in progress from the Safeway supermarket:
You’ve still got time to shop
Add items until your shopper checks out
The intent is to convey the oldest intransitive phrasal verb check out: you can add items until your shopper has completed their search for items, informed the service of this, and left the store — 1b in the OED list below. But there are three other readings for check out, and the one that came to my twisted mind first was 4c ‘to die’. Evoking images of the fatal grocery order, which will never get delivered because the shopper dropped dead. (Presumably, the 4c reading had recently come by me in some other context, so it was somehow salient to me; my imagination is not normally so dark.)
