How do you decide which grocery store to shop at? Proximity to where you live? Quality of products? Variety of what's available? Price? Healthiness? All of these are viable options. But for me, I prefer to choose based on which one has the best entertainment; so if I'm going shopping on a Friday evening I like to hit up the Shaws by UMass Boston to check out the guy on the grand piano with accompanying trumpet player. OK, not really, but that does happen. And obviously Shaws must think it brings people in or else they wouldn't do it.
