A butcher may be employed by supermarkets, grocery stores, butcher shops and fish markets
I can see that. My father in law was a butcher at a major chain grocery store and at a butcher shop later in life.
Grocery stores often offer bakeries, butchers, delis, and fresh produce.
I am glad to see that butchers are making a come back at grocery stores. For to many years meat was precut and not as personal.
Yes, butchers formed guilds in England as far back as 1272.
Cool. I did not know that. Seems like a trade tradition that has been around since forever. It must take a lot of knowlege to be a butcher.
Yes,  Some areas expect a three-year apprenticeship
