I've had a few experiences in the past of buying (non-refundable) makeup and finding snapped lipsticks, cracked palletes etc. when I get home. So nowadays I sneak makeup into changing rooms and open the sealed boxes so I can quality check before buying. I did this today at a store on Oxford Street, but found one of foundation boxes was empty inside (presumably someone else had stolen it and returned the box). At the time I panicked about being accused of stealing, so just put the empty box back on the shelf and left as quickly as possible (which I now realise was stupid because they would have just searched me and found no foundation). Now I'm terrified they'll find the box, check CCTV, and identify and locate me from the footage. Is there anything that can be done at this stage?
