Two codes that will be overhead paged are code 7 which is for a manager and code 10 which is possible shoplifting.
These stores have no LP in the store. The cameras are typically watched by the manager on duty if he is in the office. The cameras feed is also outsourced to a company that has staff that view everything that happens and they will do their best for headshots for a bolo. bolos are usually kept to stores within the same state unless the amount is very large.
My store had a no chase and hands off policy, however I’m not sure if that applies to all stores but given who they hire these people wouldn’t want to anyway. The worst they will do is harass you and follow you. They will do plenty of things to try and scare you. I have watched managers outright watch people they knew had product in their hands out the door. Another tactic they will do is overhead page that the police is outside. If you steal enough and take too long getting out they will call the police. However the manager may not even be viewing the cameras at that moment leaving the camera team to just watch it happen.
Sticker swapping is easy. Start at each edge and gently pull them off. Obvious greed will usually be spotted but a 20 dollar sticker on a 40 or 50 dollar item will usually go unnoticed. If you’re going to try anything the day before the sale ends which is Tuesday or Thursday, it’s been a while since I worked there, is the busiest day. Truck day is also another busy day but varies for each store. Feel free to ask employees they don’t think anything of it.
Now easy items to sticker swap or steal depends on the store. My store had 100-200 dollar sets of pencils out on the shelf in the open till they were stolen but this was when the store just opened. So check each store. Also train sets are such an unusual item that is easy to sticker swap. Speaking from experience on the train thing my coworker was fired because of not noticing it.
Also sticker guns are not worth stealing they watch them like a hawk and setup the stickers with the shipment lot on the items as well as different colored rolls. They take it seriously and will not let employees leave if any of them are missing.
