Gen III Prius has no belts as everything is electric (water pump, AC, cooling fan, etc). Since everything is electric, you lose nothing by shutting down the engine (except heat, eventually).

I turn of other vehicles when waiting in a drive through, but probably park and go inside more often than not.

... I've eaten, shaved, and brushed my teeth in the past in my manual gearbox vehicle. That's why knee driving was invented! Portland traffic is a nightmare.
