Note these numbers are specifically about returning to the office so it's expected numbers for workplaces like supermarkets and such will differ wildly from looking at where a typical employee in these sectors will be as the vast majority are not office workers.
The companies behind the supermarkets have large back office complexes. The size of the back office tends to be proportional to the turnover of the companies. I’m Australia retail and primary industries make a substantial proportion of that.
