A `heads up' for you and any friends you have who may be regular Costco customers. Over the last month I have become a victim of a clever scam while out shopping. Simply going out to get the family's groceries has turned out to be quite traumatic. Don't be naive enough to think it could not happen to you. Here's how the scam works: Two seriously good-looking 18-year-old girls come over to your car as you are packing your shopping in the trunk. They both start wiping your windshield with a rag and Windex, with their breasts almost falling out of their skimpy t-shirts. It is impossible not to look. When you thank them and offer them a tip, they say 'No' and instead ask you for a ride to another Costco. You agree and they get in the back seat. On the way, they start having sex with each other. Then one of them climbs over into the front seat and performs oral sex on you, while the other one steals your wallet. I had my wallet stolen April 4th, 9th, twice on the 15th and again just yesterday and very likely next weekend. Again - please be aware.
