I suppose that depends on how long it takes to service each customer, I was never good at those, if a train is traveling 20mph headed north and another train is traveling 230mph headed south, what is the name of the bus driver kind of questions. But I'm not even going to worry about thinking about it, since I can't see how it has any bearing on this discussion.

Already admitted it was fuzzy math - how about if it takes 1 minute to service each?
