Scenario:
There is a queue at a buffet of about 12 dishes. You are about 5th or 6th in the queue for the buffet and just want one item which is the very last dish on the buffet. The queue is slowly moving down with each person stopping at each dish.
There is no-one at all at the buffet from dish 4 down as the latest person on the buffet is taking their time, having a chat, having a good look etc.
Is it acceptable to go past people, grab your one item at the end of the buffet and leave?
OR
Should you just follow the queue past each dish with your empty plate until you get to the last dish?
YABU - queue and wait until you reach your choice
YANBU- just go past the queue to your choice
