if we go by actualities of what the processes are in using the expandable barriers provided then teamfills can happen as long as each person is as spaced out 2 mods apart, so every other mod, 2m+ (Tesco still operate 2m+ distancing) however this was following advice of "no need for masks as government say no need yet but advised to", now it's "you must wear a mask while store is open" if store is closed it's not required by law, nor has it been enforced by the company to wear one on nights either, but team fills were banned from happening without proper distancing and hand cleansing.
