It happens once in a year (usually after I bought a load of expensive software), that I miscalculate the money that I have left until the end of the month. So for that reason I opened up a safety account. However sometimes even this account is exhausted.... in other words - I checked my finances this morning: I'm broke, with 3 days until the paycheck arrives.
For this case I have a box in my room... I don't know how much is in there... it could be 20 Euro, maybe 30 .... it's filled with 20 cent and 10 cent pieces. It's a little bit like these treasure chests in the movies.
So I went to the Albert Hein today...
The look on the cashier's face, when I paid with a bag of 20 cent pieces... I will never forget it for the rest of my life.
