For me, it may be that the toilet paper roll needs to have the open end away from the wall. I don’t want to reach under the roll to take a piece! That’s ludicrous!
That or my recent addiction to correcting people when they use “less” when they should use “fewer”
Yes.
It does unless you’re putting an entire pepperoni or salami in one piece on your bread and still call it a sandwich. I would call bread with a number of thin hotdog-slices still a sandwich, too.
Nobody calls papperoni sausage when it is on pizza though. That is consistent with your example that a sausage is generally called a sausage only if it has not been sliced.
Except for summer sausage.
Honestly the biggest takeway from the whole discussion is that what we call food is completely arbitrary and just people going along with what the most vocal people are saying. Which is true about any informal communication.
