Water in yoghurt pots

I keep going places in Turkey where water is given to you in these little plastic containers, like yoghurt pots. It probably uses less plastic than a small bottle of water, so that must be 'a good thing' if that is the right comparison. Only, I think that the alternative should be either filtered tap water or else a large bottle of water. Unfortunately, I've been in a few restaurants where the water is poured into your glass from a really small bottle of maybe just 200ml. I grit my teeth when I see it...
