No one disputes this. And no one is advocating that you answer the phone, see what the trip is, evaluate it based on your preferences and only then decide if you want to accept it or not, all while you are in position and available for it regardless.

But your unique and extreme interpretation implies that if you have a blanket GS in, you can't have a drink. Or have child care issues come up. Or be on the road anything further than SC distances, or something. That is plainly false. Heck, if that were anywhere close to being true, then you couldn't have a blanket GS in at all, even if you lived 15 minutes away with bags perpetually packed, because you'd still need rest, so you could only blanket GS one base at a time for 14 hours max at a time. Right? Come on.

In fact, not only are you required in such an insane fantasy environment to pre-block a 10 hour rest period, you're also therefore required to whittle down your max duty day for any potential GS even during the time you're willing to do it. So every hour you'd better adjust your GS preferences to take an hour off what you can do, etc. Right?

Come on.

So of course its not a proffer. But if you can't physically (or legally) do it, then you can't do it. Answering the phone changes nothing, nor is it any form or fashion of misconduct or guilt in such a case.
