Sakaoduan Chaihohng, 48, the owner of the shop, was slightly injured to her legs and hip and taken to a nearby hospital.
The woman was preparing grilled chicken when the accident happened at 6.50am.
The pickup driver, Supachai Piasai, 27, said he had been driving his daughter to school when another pickup cut across his path, forcing him to swerve to the left and crash into the shop.
A witness told police that Supachai’s pickup had been speeding so it could not stop in time when another vehicle changed lanes to try to park on the roadside.
