@Radu I have a hunch the only reason I miss it is because I grew up with it.  The cashier told me the price and I thought find a quarter--you have a lot of change. It's just been engraved in my mind .25 is a quarter and even though I know there is no quarter in Bulgaria, I found myself looking for it. It's just funny how things like this work.  What you <em>know</em> is often over powered by instinct. And in my case it was this: Quarter, quarter, quarter. Find a quarter.
