Unless you formed a line at the end of the curb, no one cut you in line. I wouldn't expect anyone to try and keep track of who was at the bus station before them, nor pay any attention to it. As long as there was no pushing or shoving I don't think anyone did anything wrong. None of the moderate or deluxe resorts have lines at their resort bus stops, and I know not everyone likes that system. If you are in a hurry to get to the park you need to stand by the curb to be sure you get on the bus when the bus stop is busy.
