Drive throughs. WHY CAN’T I NOT STUTTER DURING A DRIVE THROUGH?!?!?

Drive throughs. WHY CAN’T I NOT STUTTER DURING A DRIVE THROUGH?!?!? There just something about it lol. Whether it’s not seeing the person, speaking to a box, or what. As soon as I hear the “Hi welcome to ____ what can I get you?” I ALWAYS stutter. Even on words I normally don’t. Anyone else have this experience?
