70's Film: Zombies Trapped in Ralphs Grocery Store

I went to a horror movie in Texas and they showed an excerpt from a 70's zombie movie. I want to know the title.

A girl with brown hair runs into a Ralphs grocery store. She walks down the aisle and sees a bunch of zombies chopping down meat. She tries to run away but is locked in the store.

I want to rent this movie. It looks so creepy.
