I contacted Wirelesswaiting for more information on the product and I was surprised at how inexpensive it really was. A 32-button receiver is £500 ($775) and each wireless button itself is £40 ($60). Obviously installation is straightforward, with only a power socket required for the receiver, as the wireless call buttons are battery powered. From their experience, customer spend typically increases by around 10% and Wirelesswaiting points out that this additional spend is usually on high margin items such as drinks, teas-and-coffees and desserts.
Obviously, this isn’t a perfect panacea as inattentive staff will always be inattentive staff and I suspect that I would be an even more annoyed customer if when I pressed the bell, no-one appeared. Overall though, it seemed to be a good idea that improved the dining experience. Apparently these systems are commonplace in Asia but this was the first time I’d seen the system in the UK so it will be interesting to see if it appears in more restaurants and diners. I can also imagine applications in other service areas, such spas, clubhouses, nursing homes and hospitals.
