Self-service kiosks will be the wave of the future as businesses look to serve their customers in better, quicker and cheaper ways.

Coca Cola now has a new kiosk that allows people to make custom beverages at the touch of a button. Clark is always annoyed if he can't make his own soft drink when he goes into a fast-food restaurant. He wants the perfect mix and only he knows how he likes it!

Associate producer Joel was in a Sam's Club recently that had one of these new Coca Cola kiosks. The first time you use one, it's befuddling and overwhelming, much like it was with early airline check-in kiosks. Yet now between 75 and 80 percent of people use the airline check-in kiosks.

Likewise, The Dallas Morning News reports that Hertz now has 80 percent of its customers using kiosks to rent vehicles. Hotels are starting this too. Restaurants are the final frontier. Clark predicts that we'll soon be placing orders and paying for meals via kiosks at mid-priced restaurants and below.

Meanwhile, the consumer champ was in a home improvement store over the weekend. As it so often is on the weekend, the place was packed with people just milling around. So while others waited in long lines, Clark went to self-checkout and was in and out in a flash.

The flip side to this whole discussion is that some people look at kiosks and say, "Whatever happened to service?" But isn't putting in a kiosk to do things better, quicker and cheaper actually serving the customer?!
