I have previously worked as an Event Assistant, Cashier, and Concessions., and am interested in applying for any similar employment opportunities with your Staffing agency. The Event Assistant position has required working at the Jacob Javitz Center, plus other previous experience setting and picking up after conventions and trade shows, gives me the experience necessary to work your job. The Cashier/Concession positions were worked at Venues in the Metropolitan NYC/New Jersey area., all should give me the experience necessary to work for your Staffing Agency, too!
