Free slide rule use
Luring consumers into a restaurant may be the challenge of the moment. But shooing them out can be difficult, too, as a Thai restaurant in San Antonio can attest. The availability of free Wi-Fi prompted some guests of YaYa’s to use the place as a second residence, a common problem for places that offer the amenity.
YaYa’s hit on a way to tout free Wi-Fi service without encouraging campers to move in. The password is the answer to a mathematical equation right out of “A Beautiful Mind.” If the place likes a customer, it can provide the answer. Otherwise, patrons can struggle to solve for P, which stands for password.
Or they can shift to a Starbucks down the street.
