Okay, then let me rephrase it: When “nearly half” disapprove it can (and probably does) mean that there is still no majority (or plurality) approving, which is what OP falsely concluded.

To be fair here and without looking up numbers, such polls tend to often show the same pattern. Something like 45% A, 30% undecided, 25% B.

So when “nearly half” disapprove it can still mean “a majority” does.

And yet the shop owners will see this and then decide to just reject reality and still complain anyway about all those imaginary cars constantly stopping by to buy something.

No, it’s literally just a bus that isn’t legally one. So they can get away without meeting basic requirements for a bus.
