Believe it or not some people pickup and drop off friends and family members at the airport. And someone like you prefer your family to take a cab. Everyone deserves to have a choice. As for my self, I like to enjoying dinner with my visitors before I take them to the airport. Just my personal preference.
I do respect choices, you didn't read my post. By all means you can leave your family and friends waiting until the traffic dies down, or send a driver. Whatever your prefer.
