I call them "Whorefoods," and they have another popular nickname:
Once a guy ahead of me in the checkout line was aghast at what his salad bar purchase ended up costing him.
Guy ahead of me: "$9.73??? I thought it was $5.99."
Cashier: "$5.99 is the price per pound."
Guy ahead of me: "Sheesh. $5.99's bad enough. Oh well."
Me: "Why d'ya think they call it 'Whole Paycheck'?"
Guy ahead of me: "No shit, huh?"
They've long since caught on to their reputation, though, and have rolled out a line of generic stuff. The brand label to look for is "365/everyday value." I divvy up my grocery shopping between the local Whorefoods and the neighborhood food co-op and the better-priced supermarkets. Knowing what to buy where keeps the food bill lower. And especially with the generic-label products Whorefoods is actually competitive for economy sometimes.
Salad bars are big money makers for grocery stores, whether they be mega-chains or those small Asian-operated holes in the wall that have proliferated in NYC especially. Even the dressing you drizzle over what you've put together adds weight.
It doesn't pay to have good taste in food.
