An analysis of calls for service from 38 convenience stores in Austin, Texas, indicates that gasoline drive offs account for 48 percent. In addition, gasoline drive offs are concentrated among a very few convenience stores. From the perspective of convenience store owners, the drive off problem is primarily a nuisance; they can recover their losses through insurance claims and higher prices. Costs to the public, however, are much greater in terms of police time and financial resources. In linking environmental characteristics and business practices of convenience stores to reported gasoline drive offs, the author suggests that removing signs from windows, installing brighter lights, and instituting a pay-first policy can deter such crimes. 33 references, 3 notes, 3 tables, and 1 figure
