Dairy Queen

My spouse and I have visited this location a number of times as it is next to our home. We have purchased a few blizzards that are consistently subpar with flavours blended only about 1/3 of the way through and the last 2/3 just plain ice cream. At first we attributed this to a one off as they were not all like this but after our third time we said we would not purchase these again. Tonight we have the location another try and I ordered a large sundae instead. When served my husband asked if it was a large because it was very small. He confirmed that the cup size was large but the serving was quite poor. We will not be returning to this location again.
