When something would be bought reminds Coco of the OSSIE story from the DDR era:

A woman is walking down the street and sees a queue outside a shop. Without another thought she joins the queue and proceeds slowly, but effectively to the counter, whereupon, being faced with an empty counter and not being entirely sure what might be being sold in the shop, she asks for a 100g, or however much she would be allowed to purchase if less, of cheese. The counter assistant replies with as much deference and respect as in the circumstance she can muster: I am sorry, Madam, we have no cheese. We are a butcher’s, and we have nothing to sell today. The queue across the road is for the shop that cheese to sell has none.
