I've seen implementations of this trend in Switzerland at natural markets - I wouldn't exactly call it "zero waste", but some shops are catering to customers who aspire to be more environmentally conscious. For example, products that keep well, e.g. olive oil, liquid shampoo and conditioner are available in taps, and customers can bring their mason jars or the like. Paper or compostable bags for the produce. Grains / nuts available by weight like in old school co-op groceries.

I don't think zero waste is feasible for the entire product mix, and we can always wonder what's happening higher up in the supply chain, but some customers definitely enjoy dealing with less waste and will prefer to shop in a store that facilitates this.
