The greeters at mega stores don't seem to have much value other than to get old semi handicapped people out of the house.
But they could be of much more value.
How many times have you arrived at the mega store & realized you didn't bring along your list? So, here's the plan - Have the greeters hand out shopping lists.
This could be done a few different ways. The store could create the lists & print them out. The greeter could make up lists & print them or just hand out hand written lists at random. Probably the best idea (and most green) would be to have the greeter collect used grocery lists as shoppers leave and recycle them, giving them out to incoming shoppers who forgot their lists!
It could be a real win win plan.
