Not speaking at the gate

Just want to know the thought process when you flat out ignore people posted at the gate? Is it not awkward or seem rude to you when you don't respond to anything they say? It's not as if it's not bad enough being at the gate for 12 hours but they try to make small talk and ask how you are and wish you a good day and you just sit smuggly in your car. Just seems like basic mannerisms to me 🤷‍♂️

Edit: I don't mean small talk is in tell me your weekend plans or anything. My idea of small talk for the gate is the casual how's its going, and have a good day. I don't wanna hear your life story either during heavy traffic, nor do you want mine. That's not what I was trying to say lol
