HA! Here is what I propose... let it be a transparent process. Give people a number like at the DMV so you know where you are in the queue. If you want to complain about logistics then give everyone a batch number and fill those in order and assign everyone who orders a batch based on location so everyone knows where they are at in line. Wanna bet it would reduce the number of chats and calls each rep gets?
As it is people can say it is first come first serve, but clearly there is more to it alls I ask is transparency so people stop wigging out.
