The man tapped his card on the gantry. The light on the gantry turned green, the gate opened and he walked through.
His wife tapped her card on another gantry. The light on the gantry turned red and she was unable to pass through as the gate remained closed.
An indian staff saw what happened and walked towards the faulty gantry to check.
The lady tried to tap her card on the gantry her husband used and nothing happened.
The staff turned to them and said, "Go counter, go counter."
They seemed to ignored her and the lady continued tapping her card on the gantry.
The staff repeated, "Go counter, go counter."
The husband replied in a loud voice, "She don't know what to say."
The staff then said, "Go to the counter and give the card to the staff there. No need to say anything. They will know what to do."
Then the man spoke to his wife in mandarin who then went to the counter to have her card reset.
