In restaurants because people have to stay seated, so easier to maintain distance. That said Im ok with a return to take away only for a few weeks.
People playing pokies are generally drinking and swapping machines, At a minimum they should have to wear masks, limit of drinks to 1 per hour, stay at one machine and have covid marshalls on site to wipe down machines thoroughly between customers.
People at places of worship move about for communion, literally accept food from the hand of the priest in the case of communion, shake hands,, sing (which projects droplets further). Im glad recommendation is to wear masks, but really ought to band any communion or touching or singing. Plus many delusionally think their god will protect them from Covid.
WRT Gym, although they may clean down the surfaces from sweat, people doing heavy exercise breathe heavier and can project droplets much further. Wearing a mask while working out isnt feasible so they should close for a couple of weeks til our numbers drop. Ive seen many oldies ta the gym, its not all young people.
