Thanks for this report (and the kind words).
It really is a one bag restriction. However if you are swift and look like you know what you are doing, then putting 1 bag per tray may get overlooked. Putting 2 bags into one tray is asking for trouble. Good old ShortyD used to keep his bag in his jacket pocket and fold the jacket into the tray, not saying this is wise or right but that's what he did.....
