My wife and I were coming back from Jamaica and one guy wouldn't put a bag under the seat. We were already taxiing to the runway and we had to go back to the terminal so they could take him off and find his luggage.
In the 90's I was flying from Norfolk to EWR. Suddenly there was a loud Jersey accented voice yelling at the FA. A guy in a wife beater shirt was yelling back at the 2 FA's who had politely asked him to stow his carry-on. In the middle of the taxi the pilot announced that he would turn the plane around and return to the gate if all bags were not immediately stowed. The glares from the front half of the plane and the catcalls from behind him convinced the blowhard to stow his bag. But he continued to be belligerent throughout the flight....in his mind he probably thought he had won the day.
