Pennies from heaven

I don't know why I all of a sudden thought of this (probably because I was balancing our checkbook...or whatever our bank account is called, since checks don't actually exist here). Anyway, there's no equivalent of a penny here--the minimum denomination is 5 Rappen (the Swiss equivalent of cents). I noticed this the first time I went to the gas station and saw that 2 Raps were added to the total to make it 70.25 instead of 70.23. This seemed like a ripoff until the next time I got gas and they deducted 2 Raps instead. So I suppose it all evens out in the long run, and it saves the hassle of having to carry one-Rap coins.
