It's not even just the "unexpected item in bagging area" factor, it's that there's often way to little staff around so you spend >5 minutes waiting on any issue, sometimes more than once ("unexpected item" and then later alcohol/age check). They have exactly the same machines in Ireland and New Zealand (just with a different colour scheme, depending on the store) and while they're still crap, they're significantly less frustrating to use than Tesco or Asda in the UK because there's usually enough staff. That's been my experience with it anyway.
