You can imagine it's like being at a grocery checkout stand, where one line is way too long, so you self-adjust to go to a shorter line. In healthcare, though, since you can't see how crowded each ER is, the system tries to put you in a shorter line, the problem, however, is that the next checkout line is at least several miles away, if not more, and the items in your grocery cart - basically your organs - have an expiration date of a few minutes to a few hours.
