Etiquette? What's that? Who enforces it??
Though I have never had a stranger grab my wheel, it wouldnt bother me if it happened. It's my ride, my wind and if the drafter wants to ride my pace for a while, that's cool with me.
Now, if it were me wanting a pull, I'm introducing myself and will offer a pull in return. It's just the nice thing to do. Too bad not all are as cultured as we are.
