Probably this is there for such a long time, but i never noticed / thought about. A small board fixed to the trolley indicating which aisle in the store has what, makes life so much easier for customers. Instead of looking for sales staff who can help us figure where is what, this will guide us directly to the department which we will be interested in. Smart thinking , Improving customer experience - i should say !
By the way this place is Stop & Shop, Main Avenue, Norwalk.
