Customers can communicate in ASL or write their orders on a tech pad. Rather than wait to hear their names called at the end of the bar, customers look up to a screen showing when their drinks are ready. The store was also remodeled to maximize light and open lines of sight -- high top tables or tall stacks of cups, for example, limit visibility for people signing to each other. Non-signing customers are also encouraged to use visual cues. Rather than sign that the store didn't carry chamomile tea, for example, one employee waved his hand across his neck -- signaling "no" -- and then pointed to a printed menu with other options.
