I can see the driver struggling to get through the day when it's being used as you have to wait for the person in the seat to unbuckle and slide the seat back to it's original position before you can even open the bulkhead door.
It wouldnt be a struggle for me....but it would be a struggle for the sup or IE guy who would have me in his face at every stop waiting for him to get the hell out of my way. I'm big, I work fast, and I get cranky easily.
Same here, if a mgr/sup wants to come with me, I say bring your running shoes,
I deliver ~40 stops to a medical school and hospital. I waste no time waiting on folks..
and hey if the elevator closes before you get here... (take the stairs)
