The co-op I frequent in Vermont provides milk in glass bottles from various dairies. The bottles have significant deposits, but the most is $2. You return the bottle. You get the deposit back. They clean and reuse the same bottle, as is shown by the accumulating scratches on the outsides of the bottles. The co-op is the main grocery store in town, so not "boutique" except insomuch as Vermont itself is boutique. But then "boutique" just means not typical. Your implication is that it means supported by bougie people living in a fantasy land. Most of US material culture is crap. This is not by necessity.
