<human>: I'll try to keep this short. Buddy walks into a large supercenter-type grocer, goes back to electronics. Puts a 2GB thumb drive and Office Season 2 into his cart. Continues on with his "shopping" and sets a big thing of toilet paper on top of the two small items. Pays for only the TP at self-checkout, chooses "leave in cart" option, then starts to walk out. Beeper sounds. Greeter shouts for Buddy to go back in and produce receipt for a check. Buddy pushes cart inside store, pulls out paid-for TP, and briskly walks out to his car and drives off, not looking back.

Of course, Buddy used his credit card. And he's pretty sure the store lot was surveilled. What are the chances Buddy will face a reckoning? He's pretty pissed to have screwed up his "brilliant plan," since the store is pretty much the only one in town with decent grocery prices, and it's an area chain, so according to Buddy, they all have his photo on a CCTV screencap by now.

Can you provide a brief overview of the text?
<bot>: Buddy pays for some items and "forgets" to pay for others, gets flagged by greeter, walks out with only paid items. Paranoia justified for return visits?
