Its not our fault its HEAD OFFICE

A week ago, I went to the Sausage saloon in N1 City.<br> <br> I order a jumbo sausage that is advertised as R25, this is below the counter and is very big. After ordering I give my R25 and leave. To be called back in front of other clients to be told I paid short. I told them the price is very big it says R25 YES WE KNOW, BUT HEAD OFFICE HAS NOT COME TO REMOVE IT THAT SPECIAL IS OVER. My question is who's problem is that. They wanted there R10 and said I need to sort it out with head office.
