Andrew Scott stocks sweet potatoes in the produce area on Tuesday at the Alfalfa's on Broadway and Arapahoe Avenue in Boulder. A senior leadership upheaval last week at Alfalfa's Market - a two-store local grocer that is a reboot of the popular natural foods chain of the 1980s and '90s - resulted in the firing of three managers and the forced resignation of CEO and Chairman Mark Retzloff, an industry veteran who co-founded both iterations of Alfalfa's.
