Why cashiers at clicks not allowed to sit down on chairs

<p>I am worried about how clicks don't allow their cashiers not to serve customers sitting on chairs like really who on earth will spend the whole day standing? I wonder why pick n pay, shoprite and spar just to mention few allow their cashiers to sit down when serving? Ooh it is because they love their stuff... Clicks must do the right thing and stop to abuse our brothers and sisters.</p>
