It's G for Ginger in North

It's my week off and I went to the Dental college near Kengeri to have my teeth fixed for free. While returning, I thought of coming en route Uttarahalli as the stretch has pleasant scenery and free from traffic. After waiting for a while for Bus, boarded a call center cab, a Winger. As we reached BGS hospital, some North Indian students, got in the cab. One of them said, "Yeh WinJar hai na?" Then his friends replied in chorus "haan, yeh WinJar hai". I guess it's not G for Grape, but G for Ginger in North.
