Solid Gold Lettuce?

I went into Whole Foods earlier today to get some crackers, as I was passing by there on the way to the bike shop, and found myself in line behind a woman who was buying just a few items, including a small package of smoked fish and a salad in a clear plastic container. I wished I'd taken a better look at her items before they were bagged when I heard the clerk tell her her total was $120!
