For those with a hard limit, assume for a moment that the posted time was your 'max' limit when you got in line, but when your max limit is reached, you still have some time in line remaining (let's say you estimate 15 more minutes before you get on). Does not mater the reason why the time was off Do you get out of line at that point, essentially wasting all of your 'max' time up to that point, or do you see the delay through even though the ultimate wait will be outside your stated boundary.
