From the post:

MODERN TIMES RETURNS
WEDNESDAY, AUGUST 26TH 9AM - 3PM
WE ARE COMING BACK AS MODERN TIMES.
POST-MODERN TIMES IS EVOLVING AS THE PHILANTHROPIC HEAD OF OUR RESTAURANT.
PRICES ARE RETURNING TO THE CAFE.
WE WILL RETURN AS A NO-TIPPING ESTABLISHMENT.
UPON RE-OPENING, WE ARE INTRODUCING AN EVOLVING TAB SYSTEM THAT WILL SERVE AS THE PRIMARY FOOD-ACCESS ARM OF OUR CAFE.
WE WILL START OFFERING (25) FREE MEALS EACH DAY.
MORE DETAILS WILL BE PROVIDED SOON.
WE HOPE TO WELCOME
YOU ALL INTO THE CAFE SOON.

Not sure I understand what an evolving tab system means, though.
