Cant believe I got away with the $200

Got a new drone and put it in the box it came in, I grabbed 6 bottles of whiskey and put them in the box as well. The drone being 200 I thought it was a safe thing to use, I walk by 2 employees and they dont say anything, I scan the drone and I'm like "oh sick, I'm in the clear" I walk out the door and no alarms, and the employee at the self checkout says "have a nice day sir" like wtf I couldnt believe it, I grabbed the liquor and ran to my car and took off, I got the whiskey for cheap<br><br>EDIT: I found that the alarm only goes off IF you walk over the sensors before the employee lets you go through, if you walk through the sensors AFTER the employee lets you through then it wont go off
