Stadium Vendor Hawks Beer Via Twitter

Might the days of "Cold beer, here!" be numbered? One beer vendor at Seattle Mariners games is turning to Twitter to supplement sales, reports CNBC. Starting with Friday's home-opener at Safeco Field, fans can tweet vendor Kevin Zelko here with their seat location, and he'll come by with their brew.

“Since the beginning of beer vendors, we’ve been walking up and down the aisles seeing who wants a beer, I’m going to try to change that,” says Zelko. He'll still make his usual rounds but check his phone frequently. Zelko says he's not worried about pranksters sending him on fake runs. As an added bonus, he figures people with smartphones will have more money to spend on beer and tips. (More beer stories.)
