Airports, where people become exponentially dumb...

Okay, you are sitting in an airport waiting for your plane to board. Suddenly, the intercom comes on inviting the first 5 rows to board the plane. How many people get up? The 20 who actually have seats in the first 5 rows? NO! About 60 overly eager people feel the need to stand in line waiting for their rows to be called. Not only are they making fools of themselves, they obstruct the 20 people who are allowed to board the plane at that time from boarding, slowing the process immensely. Furthermore, why are people wanting to get on a cramped airplane so quickly that they are ensured a seat on? Why wouldn't they want to spend every available second in the terminal where there is space and comfort? 

From this point everything seems to run smoothly until baggage claim (I no longer check my bags for this exact reason). Passengers rush over to receive their luggage and get as close to the carousel as possible, blocking the view of others, impeding the ability to pick up luggage if you are not in the front row, and obstructing the person next to them from pulling any piece off of the carousel. It makes no logical sense, but everyone does it.
