In this paper we present a toy model of single field inflation in which the standard non-Gaussianity consistency condition is violated. In this model the curvature perturbations on super-horizon scales are not conserved and the decaying modes of perturbations are not negligible. As a result large local non-Gaussianity can be obtained in the squeezed limit.
