Unless you are entering buildings with metal detectors or subject to search the key word is DISCRETE. Assemble gear you trust that is carry friendly and KEEP IT THERE. How did your coworkers observe your lighter?If you were gallant lighting somebodie's cigarette who did it help? Thats like providing pens to interviewing job candidates or telling the time to a coworker. <img src="/images/graemlins/wink.gif" alt="" />
