I think it would be awesome if you all could place a kiosk somewhere in the store where customers could input their name, phone number, and the department they needed help with. When an associate was available, they could select the next customers name and the customer would get a text saying "Harry is ready for you" in a designated area in that department. This would allow your customers the freedom to browse the entire store, while still being confident that they were on a list for help (customer given 5 minutes to arrive at designated area). This would cut down on customer frustration as they sit there and watch the employees getting swarmed with more agressive customers. This could also provide a valuable metric on the average time a customer has to wait in each department to get help.
