Never, ever, EVER stop at the top of an escalator or at the end of the 'moving sidewalk.' You will get glared at, yelled at, or plowed over. This is like the keep moving lane on the highway - keep going and MOVE WITH A PURPOSE!
If you race up to security 15 minutes before your flight, there's a good chance you WILL NOT make this one. Don't get all huffy and impatient. You're the one that didn't allow enough time. Lack of planning on your part does not constitute an emergency on mine. Don't expect all of the other passengers to accommodate your stupidity!
It is important to understand that the sky cap under the airport is NOT the TSA. It is NOT a good idea to try to run through security to make that flight in 15 minutes. You WILL get tackled.
If you are staying at a hotel with a large group
If you have to go through the metal detector 3-4 times because you "forget" to empty your pockets, take off your belt, tell the TSA agent about the metal plate in your head, you should NOT be flying.
If the gate agent or flight attendant tells you that your bag will have to be checked, don't argue. Shut your mouth and comply. Perhaps you should consider purchasing a bag that will actually fit in the size/check dimensions contraption.
While riding the Park & Ride bus in Atlanta, stay off your cell phone long enough to pay attention to the driver. The driver will call out the row on the ticket and you will tell the driver what the make/model of your car is. The driver will deliver you right to your car. IF you are rude and spend all your time on your cell phone, the driver will move right on by your car. Do NOT pipe up and say, "hey, you passed me up." YOU passed up yourself by yammering on your phone at an inopportune time!
Also, while riding a packed Park & Ride bus in Atlanta, you do not need to take up two seats. Close your legs, put your brief case with the skinny side between your feet, and face forward...and hang up your cell phone, please!
Lastly, NO ONE WANTS TO SMELL YOUR STINKY FEET! Do NOT take off your shoes in the terminal at the gate, in your seat on the plane, or anywhere near other passengers!
