Dear Dunkin' Donuts Drive-Through Lady

"I appreciate your kindness this morning when I stopped by for my morning coffee, however I surely hope you did not charge me extra for the coffee grinds included in my coffee. I remember specifically asking for a large coffee extra light and sweet. Not large coffee extra light and sweet and gritty. Since I have to use a straw to drink my coffee because all the sugar settles on the bottom so I mix said coffee with a straw you can imagine my joy when I went to sip my coffee with my straw and got a moutful of coffee grinds. Once I realized that those granulars in mouth were not undissolved sugar cystals I ran my coffee through a spare coffee filter here at work. You are lucky that I do not have my camera or you would be shocked to see how many coffee grinds were inhabiting my coffee.
So, next time, as much as I appreciate your kindness and generosity, please keep your coffee grinds to yourself and out of my coffee.
Thank You."
