To Graham #2179 from Australia. That yellow item as you put it is a wheeled cask. During the Soviet times the government used to sell kvass and beer from such casks. It is still sold nowadays, but not that much as it was before. Particularly in that yellow item next to the white wall, a woman from the milk factory that is right behind the white wall sells a milk product. Unfortunatelly I forgot its name, I think it’s ryazhenka or something like that, and I know that it is very good for you. Michael
