Actually asking for a friend here. Friend works at a job where they are not allowed to take anything into work with them. They go through metal detectors and a light pat down before entering. Once inside they have to are forced to make unhealthy food choices out of a vending machine for meals. Friend is looking for some ideas of what to hide in a pocket that will make it past the metal detectors, a light pat down (the high is below 20 here today so bulky coat weather) and be healthier than vending machine but still pretty filling. Any ideas?
