The Marewa Four Square in Napier was targeted by a grab-and-run thief this morning.
The incident happened about 9.40am.
Two teenage girls had just left the shop and sat down nearby when they saw a person dash out of the shop and down the footpath.
"She was sort of tubby and had a black hoodie on," one said.
They were not sure if she was carrying anything.
"The manager came out and chased her down the street and around the corner - he came back later in a police car."
A police spokesman said while no arrests had been made at this stage they had a "suspect in mind" and were looking for her.
It is understood the woman grabbed several food items then made a run for it.
