I havent see anyone post that they cant remember what their pie tasted like. If some people say they have not noticed a change and a fair few, which i would take as more than some, saying that they are not as good. I would say is "a general consensus"
Of course they would deny it. However it is their word against those that eat the pies and the general consensus from this thread is that the pies are not as good quality as they used to be.
