If this ever actually happened, I'd be much more likely to volunteer for back-up. As it is, with hours being cut recently, I barely get my truck and back stock done before I'm supposed to be out. So the idea of responding to a back-up call and getting stuck on a register for a half-hour (or more - it's happened, plenty of times) is not attractive.hmm. How about that? My DBO backs up for 15 minutes, a cashier returns to their department when they are finished to push for 15 minutes.
DBO more likely to assist.
I get that guests don't want to wait in line forever. But they kinda want to find stuff on shelves too, or they won't have anything to get in line for.
