No, they did measure them, they just didn't bother to value them. People are spending less time in the restaurants (<10 minutes.) People spending time in the restaurants are getting service (cleaning etc.) and use of the space/dishes. They aren't accounting for these services.

I’m not sure I agree it’s entirely measurable. Often when something becomes more productive at the expense of something, that something is the comfort of being in the place or the friendliness of the staff or… and these things are intrinsically tough to measure. Not unmeasurable I suppose, but challenging by comparison.
