Sour Pancakes

I went to buy pancakes and when I got to the pancake station there was no one there. I asked security if there was someone available and he told me to go to the Deli section (why do I need to look for someone to provide me with service?). I eventually got someone to help me.

When I got home and tried to enjoy my pancakes, the pancakes tasted sour. Mind you, I only live 5 minutes away from the store so they couldn’t have gone off from the drive.

Why are the pancakes sour???
