A single line servicing multiple tellers is the fairest, and results in an equal wait time for all involved. Multiple, single lines for each teller result in a wait time dependant on the speed of the teller.
Years ago, before Cedar Fair took over, Canada's Wonderland used to build maaaaaasive stations for their coasters with long, individual corrals for each seat on a train. This meant that each cycle, you would only advance two people. So you'd physically move about two people every minute or so, which is agonizing. A "platform wait" at any other park might be 10 minutes, but at Wonderland, you might have spent an hour waiting in a horribly crowded situation like that.
Now, the standard is to build platforms with only one-train's worth of corrals per loading slot on the train, and typically they'll even have an attendant at the top of the stairs to the station that only allows a full shot worth of people into the platform. The queue line moves 30-40 people every minute. It's strictly a mental thing, but it makes the wait far, far more bearable.
