I definitely understand what you're saying. And, I guess (though I haven't looked it up), RAW agrees with you.
But my problem with the above is the following:
Lets say you're in combat. Initiative has been rolled, and your turn comes up. You use your turn to ready an action. You point your loaded crossbow at the closed door and say that you will fire if the door opens. At some point before your turn comes up again, the door opens and BOOM, you fire! There is no "chance" that your readied action might not happen. It always happens under the context of the trigger... because you were READY.
What you're saying is that outside of combat, the FIRST thing you do is check for surprise. Then, even if I was READY to catch the flipped coin (I'm in a ready stance, my hand is out and ready, I'm staring at the coin, I'm focused, etc), if my friend "gets surprise" on me then this somehow bypasses the fact that I was ready to catch it. He flips the coin, and I DON'T catch it, because I could not possibly have been ready since initiative had not been rolled yet.
Is this really how it is supposed to work via RAW?
In the first situation, you and the other party competed to see who was fastest and you won. You pre-empted his action as soon as he began it because you had the initiative. In the second scenario, who was fastest hadn't been resolved yet- you were waiting to catch the coin, and so was your friend. The initiative roll resolves whose reflexes are faster. If there is no surprise, the assumption is that both parties realized that the other was going to try something (an attack, generally), and so quickness of reflexes resolves who gets to act first.
If you are ambushing someone, there might be surprise, so it's Perception vs. Stealth. Attacking an ally might be something like Sense Motive vs. Stealth or Sleight of Hand. If the attacker fails that roll, that means they had an indication of what was coming- your friend saw you tense to get ready to catch the coin- and now it is essentially a test of reflexes, or a roll to see which of two prepared actions gets precedence.
