Very VERY Specific

A customer came in today and asked for help with choosing a dog food. She said she was looking for something grain free and gluten free. My Asst. Mgr suggested a certain brand so we started there. We read the ingredients - no grains. But it did have peas. The dog can't have peas ... you see, peas make the customer itch, and the dog has allergies, so since She (the customer) can't eat peas, neither can the dog. Ok then. On to the next food ... reading the ingredients .... no peas, but it has tomato. Nope ... no tomatoes. No explanation, just No. Moving on ... here's a food, no grains, no peas, no tomato!  We have a winner!  Hmm ... but it doesn't have rice.  We must have rice. So, let me get this straight; we need grain free, gluten free, pea free and tomato free, but must have rice?? After reading the ingredient labels for almost every food we carry, she picked a bag of food that was shiny and pretty - guess what ... Grain free (aka no wheat and no barley), no peas, no tomato and had rice.
