It's a good idea that most fast food restaurants are utilizing dual drive-thru lanes. However, when a customer asks for just a minute to review the menu, it does not mean take the next 4 vehicles in the other lane, before coming back to the waiting customer. The car behind me even reversed and went to the other line and was assisted before we were. When I stated I was ready (3 cars in) the person stated they would be with me shortly....I would suggest better training of the dual lanes so this doesn't happen to future customers.
