If they’re doing the orders by the time they were received, then it’s no different than standing in a long queue for people to order. It would probably be easier to bring back the number ticketing system, but regardless it should not be different than people coming into the store and standing in line. If they’re doing the mobile orders first, then that’s most likely a contractual obligation that these employees have no control of. No offense, but as a whole society we now expect ourselves to receive service instantly and any form of delay is inconvenient and frustrating. I get it, but patience is a virtue
