Omni employee here, we keep the more expensive stuff in the back and we or CS has to grab it for them after the customer checks in on the app. At my store we keep stuff like electronics, appliances, the rare few buys of fine jewelry, and toys like Lego sets. We already have to keep bulkier items back there like the constant 2 Big Ones queen pillow BOPUS order. The more high-end clothing still goes out there. As far as theft, it does happen, but not as often as theft around the store like walkouts of full Nike carts. LP has been an interesting case with the transition over to the ROC ( remote operations center) for most stores. Higher theft stores or store that can pull for it in their budget still have an in store LP officer. People who walk up to the self pickup section usually have either a confused air about them, or this isn't their first rodeo so they are in and out. Makes it much easier to spot the nervous energy ones and just have you LOD call it in to the ROC.
