Agree on withholding the pepper spray, even though I get the urge to use it …
But I think the situation is another layer to the ‘waiting room’, and that’s after the exam is concluded and the owner is going through the checking out procedure.
My last vet had modified that as well, to make use of portable payment devices and have owners check out in the exam room, away from other animals.
Because that’s a whole other awkward scene, depending on the owner & pet being back in the waiting room at the front counter to review the bill and pay, or doing that at a counter elsewhere. Other pets are coming and going and/or, of course, back into the waiting room scenario.
The most awkward part is that it’s not usually feasible for the owner to first take the pet to be stashed, alone, in a now-hot car. While the owner then returns inside to review and pay the bill. Where I live a car sitting in a parking lot will be an oven even on many winter days. And of course leaving the pet alone may not be a great idea, either.
I think the conveniences of modern check-out options, and continuing to use exam rooms to keep animals separated, is likely the best way to go, at this point. Hopefully clinics are thinking about this as well.
