Chee

 Chee is how you pronounce QI which will be what all your customers are demanding from you in the near future.  Wireless Charging at their table.  The latest phones (such as the Samsung 6) have the charging system incorporated but for the rest of us there is a device that allows you to plug in and recharge your phone.

 Chee - Get with it!
