Inventory shrinkage (theft) is one of the largest expenses a business can experience...and (example) hotel/motel customers should realize they're just
renting amenities...not buying them.
As for the staff not noticing the larger items going out the door ??
"Ha"...around here entire chains of stores etc have left the city... partially because all too many locals have gotten so good at shop-lifting they could just about walk in naked

and walk out hiding something.
