When I was in SFO RCC lounge last Friday, I saw a small note below the Air Canada sign on the list of *A members: "Maple Leaf * No Guest."

I asked the agent what this was about and he told me "It's just that at SFO we don't allow guests."

As I was in a hurry, I didn't ask them to explain more clearly. This note is ambiguous and could result in many possible meanings

e.g. No Maple Leaf Guest Pass

or worst case

no guest for AC E/SE


Have any of you noticed the note and know what exactly it means?
