I was the asst manage of three back in the early 90s. It's different today. I did get a part time job there last summer and hated it. I never should have been hired and the other kids there took advantage of that fact.
Normally, it's 3 slices of meat for a 6 inch. Some it's 4. Only 2 pieces of cheese for a 6 inch still. I think the bologna meat you get more, but I don't remember anymore. I never ate that one. Meatballs, it's only 4 as well. Everything else is up to you but the olives. Per Subway, you're only supposed to get FOUR olives per footlong. They're really expensive.
