Yes, it happened to me at Safeway. When we realized we were looking for each other, he bent me over one of the checkout stands (it was not in use) pulled off my pants, and fucked me right then and there. Then I sucked him off (wouldn't you know it - the checkstand is JUST the right height.) As I was savoring the last drops of cum, the hunky assistant manager whipped out his dick and took of his shirt so I could worship his muscles while going to town on him. As he came he braced himself on my shoulders and that's when I saw a circle of customers had formed around us and they were all jerking themselves off. Unfortunately, they couldn't hold off and we had a very wet cleanup at register seven.
Of course, I am being facetious. No, that has never happened to me, I did get picked up in a Whole Foods once though. The guy walked home with me and then asked if he could help put my groceries away. He certainly knew how and where to use his zucchini!
