So at my job it is my duty to check out customers, process everybody in, but something that I also have to be watching out for is the people who just walk in and out with items that are being paid for. It's not a required part of my position, but sometimes when we get alarms and people tell us that there is somebody being suspicious or something, we have to check out customers as well as being the lookout and watching who comes in and out of the doors and what they have and asking for receipts and everything.
