That does not make any sense whatsoever!! Whatever supermarket you are in you do not have to pack at the checkout anyway. You can do it at your car, you can do it from your loaded trolley away from the checkout too. The gripe is not that Aldi, as horrible as they are, have user unfriendly checkouts, which they do. It is about the crazy speed that items are fed through them, giving the less agile and elderly no time to keep pace. It may be that one day, all those who see it as no big deal, will themselves reach a point when they too will complain. An accident perhaps. Even old age infirmities. Be kind people, and think of others less able.
