Surely then Tesco, Supervalu, Lidl etc etc customers wouldn't be happy either? My original query was what is the actual reason Dunnes are an outlier. Dunnes would suit themselves and the rounding must be something that they dont want to do. I think personally they should be told to get on with it and fall in with all the other shops in their industry.Dunnes initially started and rounding up and I think customers were not happy. I am delighted you get the right change. Don’t forget easy to cash out if the right change is in the tray at the end of the day.
