That’s because of the delay.
Especially during poor weather, surely numerous passengers would prefer to get off into the shelter of Haymarket Bus Station and straight into Eldon Sq Shopping Centre without facing the elements, but of course they’ve become used to be bus sitting at St Mary’s for an unknown amount of time, hence they just get off.
