Was there a time constraint on the length of the meal? Not anything formal, like you have to finish in a set period of time, but were there events taking place afterward that people were in a hurry to get to, or were they in a rush to go home?
I'm a fairly slow eater, and I inevitably always end up still eating while everyone else has finished, so sometimes my meal gets taken back unfinished if we have to move on to something different. Maybe you just eat faster than most other people.
Or you just had a better appetite than the others that night. Either way, you didn't do anything wrong or embarrassing, so I wouldn't worry about it.
