I second that;"not while your studying". In general, watch out opening hookah bars in North America. You should watch Spike's "Bar Rescue" Episode on a person trying to open a hookah bar in a midwestern US city of 1/2 million. To make a long story short almost every North American only showed up at the hookah bar for, "special occasions". That meant a visit maybe once every 3 years. Only very, very large NA cities can generate adequate numbers of regular customers.
