Dunnes Stores continue to give 2c and 1c in the change - both in person and at the self service machines. After the universal take up of rounding in Ireland for several years, why is Dunnes an outlier? Is it due to their accounting systems aren't geared up for rounding? I thought that rounding is "the law of the land"? Or is it just voluntary? It's not a big issue but a minor gripe of mine as a regular customer of theirs.
