Back in my day, my dear, water buckets were not able to be retrieved by any well but was only available in Brittany and a few other cities. I was living way south in Solania and had to traverse the roads through control points to get as many buckets of water I could by foot! Fighting many creatures and bandits it was a trek each time and during those early days you could not carry much. each trip was dangerous and not like the many places that sell water now.
Water seems to be the only real necessary item sold on the bartender vendor. If the cooking vendor could sell water, then I could remove the bartender vendor.
The cooking vendor should not sell water - he should need water to do his job cooking. A Waterzup or such without water is a very dry meal.
