I haave two big jars of coins on my desk colected over the years or maybe decades. I have been trying to use them up. I know what coffee costs at Il forneo. $2.03. So I bring 8 quarters and three pennies. but at Paris bakery I get the same thing every week but the price keeps shifting around between $1.97 and $2.33 depending on who is the counter person. So I just bring a handful of change and use it for the tip's jar. Slowing I am beginning to make a dent in this glut of coins.
