I've seen the "bottles" up to pint sized, or perhaps that was "half liter". <G>
WalMart in France
? Good lord, one hopes not. But then again, I understand that thermos bottles are illegal in Paris, it is only the uncivilized boors who live outside the municipal limits that think food
can be kept hot or cold instead of being properly prepared on the spot and consumed in the timely manner.
(Only half tongue in cheek, because "Paris" just ain't "France" and they're each quite upset about the other. I prefer France.)
