Could be some folks might have to catch a second plane and the timing is really close. Unfamiliar airport layout sometimes puts your connecting flight on the opposite side of the airport and it departs in 10 mins. I would be in a hurry to get off and reach my connecting flight in time.
This is just one scenario. Each person is different. Some people have travel anxiety etc.
Pretty easy to understand once you open up to the idea that you don’t know each person’s day, schedule or disorder 🤷♂️
My point still stands. Everyone is living their own lives and have their reasons for being in a hurry. Not everyone is a chill dude like you.
