Yes, sometimes even the French come up with a very simple idea, after which you think: why didn't someone do this earlier? See the receipt to the side? We got that after buying some stuff at a
large supermarket in France. The things you bought are not sorted by chronological order in which they are scanned at the check-out (what makes no sense at all), but clustered into useful groups.
So now you can easily check fast if you forgot something or immediately see that you spend much more money on booze then on healthy thingy... aaah, well, hmmm, ok. Maybe that's why Germans don't
have this yet. =)
