I love messing with customer service representatives. I just got a call from Comcast asking me a series of questions, which I was suppose to answer on a 1-10 scale. The call was to rate my experience with their billing department when I called a week ago. I had originally called because my bill was much higher than expected, so I wanted to test their math.

I started answering with decimal points (for example 3.675 instead of 3) and making her round to the nearest number. Then I went to division, multiplication, irrational numbers, square roots, cube roots and powers. I asked her to answer the math problems to make sure she could accurately rate my dissatisfaction their service. She did ok, but I still don't trust them to bill me correctly.
