Found Hair in My Mango Lemonade from Caribou Coffee After Drinking It

I ordered a large mango lemonade from Caribou Coffee, and after finishing it, I noticed something strange in the cup. Upon closer inspection, I saw that there was a strand of hair inside the lemonade. Unfortunately, I had already finished the drink by the time I discovered this. This is extremely unhygienic and unacceptable. Caribou Coffee, I expect better quality control and cleanliness from your establishment. Please take immediate action to prevent this from happening to other customers.
