Question $3$ of $3$

Same scenario as above except this time the number of items in each customer's cart is known. Here we have $9$ customers already queued up at $4$ cash desks.

Another six are approaching and must decide what queue to join. What queues would you predict customers $F,E,D,C,B,$A will join if they do so one at a time and

each gets to see where the one before went.
