Domino's Pizza review: Delivery

I ordered pizza last week and I paid with my debit card. I'm on disability so I tipped with cash, well my bank account is overdrawn now because the driver decided to tip himself $2.00 more on my card anyway. I live on a very fixed income and this is unexceptable anyway. The driver was also rude to begin with. I feel silly complaining about $2.00 but its more that i had already tipped him with cash, it's the principal.
