In the rare cases where "in car" is ordered, they provide a kit that will fit into the passenger side pocket of your vehicle and will record any theft from the car by the valet. These are only ordered when there is a reason to suspect such theft has been occurring. btw, your button cam may not be best. Because you may need to see over a counter to observe cash handling, or need to capture the attendant while you are seated in the vehicle, eyeglass cams and/or bluetooth (over the ear) can be much better at "following the money." btw, most of their valet shops are not video, btw, except in major metro areas.
