Courtesy wise. I think it's a matter of courtesy that you get the pin before you fly whether you're the only one there or not.. Isn't that showing courtesy to the other members of the club? Even though you're there first you would be the cause of the situation and it could lead to the person with the pins plane being damaged or the other person being hurt as well.

This isn't for flyintiger, i don't think he has an issue with this but I'm very suprised to see the other view...
