Had an A10 bus gate experience last week. They pontificate about social distancing in the terminal etc but then cram everyone on until the bus is full. In covid times we need the full complement of buses (or lounge space, or car parks etc) to service the reduced number of pax. Otherwise, half the pax in half the space = normal distancing.
An american on the bus summed it up nicely - they let their premium passengers on the bus first and they end up last to board the plane.
