Jeez some staff are just so arrogant. I know the type. I didn’t miss a flight over it, I was denied beer before because the lady at the store thought my drivers ID was fake, so I happened to have my immigration paper on me that day and showed her all the info matched. She said the paper expired so she couldn’t accept it, she was looking at the Landed in Canada Date, but she wouldn’t have it that she made a mistake.
