This is so funny

Conversation in the taxi with the driver along with my customer.

Me: Can you get me to the airport?
Driver: Which terminal?
Me/Customer: International.
Driver: Which airlines?
Me: Singapore Airlines.
Driver: It's either terminal 2 or 3.

While thinking how to make sure which terminal it is......

Customer: Isn't all flights in Singapore international? We wouldn't be flying from one side of the island to the other side right?
