A fast-food restaurant employee passed out during a robbery, police said.
Houston police said two armed men held up the Wendy's on Dairy Ashford near Perthshire about 8:30 p.m. Monday.
The robbers, who had bandannas on their faces, jumped the counter and demanded cash, investigators said.
One of the employees passed out during the robbery, officials said. Detectives have not said if that person had a pre-existing health condition that caused that.
Descriptions of the robbers have not been released. The store did not record surveillance video of the robbery, officials said.
