You know what grinds my gears?
When you go to starbucks and get a Grande house blend coffee... They charge you $1.96 for the coffee, You hand them $2.00 and then they hand you back 4 pennies.... Hey, seriously.. just make it $2.00 already...
The amount of coffee you get in a grande isn't even worth 4 cents.
lol...I usually put that into their tip jar, if there is one. Or I say, "Keep the change..."
