Delivery speedy

My grandmother had a saying: “A watched pot never boils.”
And back then, they didn’t have television, so I guess they did a lot of watching pots.
These days, I say “A watched deliveryman never delivers.”
He’s been five stops away forever. What’s taking him so long?
What’s with all those other stops?
When you bring up the delivery tracker from Amazon, that dot never seems to move on the map.
Unless you watch him through the scope of a sniper rifle.
And shout “I am watching you through the scope of a sniper rifle.”
Then they deliver.
And run.
