I had a 23 year old guy approach my counter at work recently with an attitude of arrogance and entitlement. (He picked the wrong person). He bout lost it when I told him he’d have to pay for an overweight bag (I work for an airline). As he was on the floor removing some things his dad approaches and the kid starts running his mouth. I snapped and said, if you had been nice when you approached me instead of rude, I might have overlooked the extra weight but you were rude from the beginning. His dad started trying to pacify his son. I wanted to punch him because he is obviously the one who created the brat, man-child.
If he had been my child, that would have been nipped in the bud when he was young. Such a jerk.
