Garfield is not a special character in this sense

Today a customer was having trouble creating a password for the state unemployment website that met the system requirements. I reviewed them with her.

Passwords must contain:
- At least 8 characters
- A minimum of one of each of the following

• Upper case letter
• Lower case letter
• Number
• Special character 

She then wrote out what she wanted to use "Garfield1963". I told her that wouldn't work since it lacked a special character. She looked at me in complete seriousness and said "Garfield is a special character".

My next job is so not going to feature working with the public.
