You have a long line of customers queuing up at the till. Would it not be great to have a second till?
As a shopper, I can assure you that it is very annoying to wait a long time in a queue. Sometimes there is not enough room at the counter to add another register, often its not worth it to buy another cash register, etc. So one point that our system handles very well is that you can have several tills on one computer.
This can help to reduce traffic pressure and prevent customer dissatisfaction It might even save some sales as less people give up waiting and leave.
Plus the speed in which transactions are done on how POS system is really something.
