我本來諗住大佢，但見佢都scan 我本passport 就算了，對話如下：
Morning, hmmm u aren't supposed to line up here. This is EU passport lane.
I know but the sign shows UK/ EU passport, that's y I line up here
This lane is for BRITISH CITIZEN passport only but not this one. They do not need to fill in the landing card.
Oh I am misled by the Heathrow website then
This time I will do it for you cuz it's no point to send you back to non eu. Next time pls go to the other lane
Ok thanks so much
Enjoy your trip
Thank you so much. Have a nice day!
