Improvisation! I missed the idea of it being more of a distribtion bar and instead interpreted as a food preparation area. Talked about the firing of grain, wheat and millet for bread, how fish caught in the Bay of Naples was guttered, scaled and cut into fillets, whilst the fish oil was extracted and used in the world famous and still-existing "Pompeian Fish Dressing"
I said that population of cooks largely consisted of slaves who prepared the food at snack bars as demonstrated in the source.
In terms of distribution, I didnt so much stress the snack bar aspect, more its distibution in the Forum. The Macellum being the meat and fish market whilst the Cereals Market selling grain products.
It will ultimately come down to whether the markers allow for multiple interpretations of what the food bar could have been for; as either a food preparation area and/or a food distribution area. I guess thats the benefit of ancient history over modern.
BTW - did anyone notice how at the bottom of each station on the snack bar, there was a large smooth stone built into the table? It looked almost like a furnace!
