A butcher with specificity

Driving through French villages we see shops that are clearly butcher shops (boucherie) but also identify in other ways charcuterie, traiteur (clearly not referring to a traitor), and other related words. The French language does tend to be rather specific with certain nuances, like boulangerie as a bakery for bread, while a patisserie is for sweets. As always, we delve into it with some internet research to determine that a charcuterie specifies that it is a butcher for pork products (important here with so many who will only purchase halel meats) and that traiteur seems to relate to catering, but specifically of pork products. Who knew?
