I agree that it's horribly cramped and busy, and though I've never needed customer service here, I get the feeling I'd have to be spouting arterial blood in the aisles before a staff member lost the glazed look in his or her eyes.
Another thing that peeves me; why is practically all the fresh produce wrapped in plastic? Why should I have to buy two packages of green beans when I only need one and a half? May I decide if my lettuces may reside in a single bag? Above all, why do I have to use all this extra plastic?
