Yup. My shortest time on the job was a day and a half.

Well..just a day cuz the half day before was just training.
To make myself feel better it was a CSR job that threw you in front of a computer, handed you a script and said 'sink or swim'. We had to lie about how we got peoples information. We were cold calling basically. I kept fumbling over my lines and they said 'We dont think this is for you'.
I've had a job like this...I quit it after a month when they gave me a paycheck for $30 for commissions even though I made $1,000 in commissions that week...
