I don’t think you understood what the GP said, but then you claimed as much…
That said, even with your interpretation, imagine that if you didn’t do something, somebody else would have to shit on the bus —- you’d have to be pretty selfish not to spend a bit of time to spare the other person of the embarrassment.
There are myriad other examples where you can take action now to avail yourself of a future mild inconvenience that you might not take if the inconvenience were experienced by someone else instead. And I can't imagine that you think telling me I don't understand what GP said, without offering clarification of your own, is a useful comment.
