What really made a lasting impression on me was their loss-prevention training me was that not everybody is strong enough to carry an item, a bag, or push a cart while shopping. When seeing somebody place an item in their pocket/purse/bag we would offer to carry it for them or hold it at the front-desk.
This enabled a compassionate the benefit of the doubt to a clientele base who were often too frail from HIV-related illnesses to hold the item in their hands and offered a gracious, de-escalated escape route for would-be thieves.
