Laziest eh? Probably the one that deletes completed items from my shopping list when I leave the supermarket, because I got sick of doing it manually.

Most ridiculous would be the NFC tag I have on the lid of my cold brew coffee jug. I make a batch so rarely that I can never remember how much coffee to add, so scanning the tag makes my Google Home say; "You want 80g of coffee per litre, or 6 scoops."
