Recent French Disappointment.

Standing in line at the Monoprix. The price is 6.80. I put down a 10 euro bill and begin counting out my .80 centimes. This isn't what the cashier wants, however, and takes my ten, gives me change and refuses my .80 centimes. &*(^%$! What the heck. I can't begin to explain how upsetting it is to deal with. If you want to give a cashier change, start with the coins and THEN put the bill down. I've done it in the past. Should've learned from my lesson.
