its funny at one regional market here, the cashiers are fed up with people being stupid and neet help or are even stealing. so sadly its disabled most of the time. at a different place, there keeps being a loooong line, but literaly noone uses the self checkout. it is so useful. if i forgot something or just gotta get coffee beans, i quickly swing by that place because i know no matter how busy it is, i dont have to wait in line xD
