My neighbor is a butcher.
Butchers are people who slaughter animals and sell their meat. That's a gross business. Your neighbor must be rough
Yeah it kinda grosses me out.
Typically butchers are employed by supermarkets or butcher shops, bust some are self employed. Is he self employed or does he work somewhere?
My neighbor owns a butcher shop.
Oh, that's a lot of work. Today many jurisdictions offer trade certificates to butchers
oh they do? Why?
It's esentially a regulation to monitor selling meat products 
Oh okay. That makes sense.
In some places, you need a 3 year apprenticeship to become a master butcher! How's that for investment?
