What is wrong wit a mandatory waving off the gliders at the end of the
tow?

Wrong is that I, the glider pilot, want to decide where to be towed and
when to release. Because I, the glider pilot, am in the air without an
engine after the release. No tuggie, no matter how experienced he may
be, will ever tell me when and where to release.

I can promise you, if, I were towing you, and you did not get off when I
waved you off. You would be wearing the rope. I have done it before,
and I still have lots more rope available to me. Aside, from that, I
will normally take you where you want to go, but if, I want you gone,
You will be gone.
