The tip jars at Starbucks really annoy me. I often see them filled as well. The workers there are paid a decent wage (for food service), why do I need to leave a tip because you prepared a frap? Isn't the $4.75 enough of a *donation* on my part. It's not as if they are waiters and depend on tips to make a livable wage as a barista. Maybe if you order something crazy like a double tall no whip mocha latte. It just bothers me that Starbucks even has the tip jar there.
