I'm not sure if this belongs in economy. Just wondering though. Is there a reason why bank machines in Ireland rarely have 20s (only 50s), and don't give you 10s? In France, Spain, Germany etc, if you take out 50 or 60 it gives you an assortment of notes. The UK does the same too with sterling. Is there a reason for this? Is it more economical for them to only give out 50s or something? Or am I just imagining all this?
