What's wrong with these people?

I was asked to take a 1-question survey concerning my call to FedEx.

"Thank you for taking the time to help us improve our customer service. Using the key pad on your phone, with 1 meaning you disagree strongly and 5 meaning you agree strongly, please rate your satisfaction regarding your call to FedEx." (or words to that effect)

I pressed 5.

"Sorry, I didn't get that. Using the key pad blah blah.."

I pressed 5.

"Sorry, I didn't get that..."

Firmly, I said "5!"

"Thank you for your time."
