Here was my short and sweet response to Quizno's.

Dear Sirs,
Your tasteless commercial aired during the super bowl game has left a sour taste in my mouth for your company. I do not understand how you can think the abuse of animals, no matter how small in nature, is an acceptable advertising ploy. I will not patronize your store any longer because of this commercial. So in stead of gaining a customer, I am reporting you just lost one.

Disgusted by your tastelessness,
Candace
