Publix is setting aside special shopping hours for first responders and hospital workers on Thursday nights from 8 to 9 p.m. and Friday mornings from 7 to 8 a.m. The pharmacy will also be open at these hours. It’s the latest in a number of changes at Publix during the coronavirus pandemic, from touch-free checkout, special hours for seniors, no more free samples at the deli, and one-way aisles.
