Honesty is the best policy!

We went to the A Chau (Gesundheit!!!) Asian Market in Basel today to pick up a few things for our New Year's Day feast. The total cost for our things was 39 francs. I gave the lady a 200 franc note, and she gave me...261 francs change!!! An easy 61 franc profit plus free Asian groceries??? Of course not! I brought the mistake to the lady's attention, and she exchanged the 200 CHF note for a 100 CHF note. My good deed for the day!
