There was a time when I found the checkers too obnoxious to bear, but it seems like there is less attitude than a few years back.
As a regular shopper since the days of the original Central Co-op, I can say that this store has certainly evolved a bit.
They are a decent medium sized natural grocery, they have most things you want, but they don't have some of the must-haves, which means a trip to a second store for the necessities. Since Trader Joe's opened next door I shop there more, because if Madison Market is out of whole organic chickens, for instance, which has happened many times, I pop on over to Trader Joe's and pick up one there, along with a much cheaper pound of butter.
As for the pricing, I have more than once not gotten the discount promised on the shelf sale tag, have been charged more than the produce tag (or the produce person indicates when I often can't find a produce price) but they will fix price errors, just check your receipt. Also, they run high on produce prices sometimes, they need a better source when their cherries are 7.99 and the farmers markets sell organic cherries for around 4.00.
I also have had a few too many bad meat experiences, and one questionable seafood incident, so every so often that puts me off of buying the meat.
But they are all we have on this side of the ship canal besides a few PCCs way down south. And they do try to get it right.
The friendly factor is up at the, now if only the workers would not block the whole aisle and half the produce department while they stock the bins.
