All walls talk, no matter the business. Walls say something good or bad about businesses every day. The problem is, many businesspeople do not spend enough time in their stores to know what the walls are telling them. Instead they rely on second-hand reports or scrutinize store-specific financials to make observations. The solution is as easy as sitting in the store and observing. Keep in mind, if you can hear what the walls are telling you, your customers certainly can.
