Passage Ticketing Ideas

I would love the option to display a running balance of the head count that is in the virtual queue. The way we operate we can only run so many people per truck and if they are in line but wanting to do other activities while they wait they would like to know an estimated time. To do this we have to go down and manually add each line to see how far down they are. So if there was a running balance out to the side after every new entry this would save us so much time and customer frustration. Easiest way for me to explain the general concept is just like a checkbook register.
