It pays to watch out for crooks, here they come especially around the holidays. The old cash-back on the receipt when you never asked for it? No money OR change offered til you ask for it twice? Those are old tricks. And even then maybe 10 is missing or it's the old switcheroo with the folded five in the change back from a 20. Watch 'em hawkeye, and spin the carousel check all Your bags are in Your cart before leaving the cashier station. If their pal is the next in line, a bag or two of your good goodies will go in that cart instead of yours, with some extra cash in their change. Raise the red flag if someone crowds, bumps, or criticizes you for not being fast enough . Whoopi-ti-yi-yo move along little dogie. O Yeah.
