One nice thing about Costco is how easy it is to return what you don't like. I went through the house today and gathered up some recent purchases for return. In the pantry I found 5 cans each of salmon and tuna. The clerk didn't question me about the metal shelves or the water pitcher, but she asked about the fish. "I just couldn't eat them," I said, "I started thinking about how beautiful the fish are and I realized I couldn't eat them." "Are you a vegetarian," she asked. "Yes," I said.
Here's some neat links about fish for those that don't think they are beautiful creatures (I wouldn't eat a rat or raccoon either, though not because I like the way they look) or do think they are beautiful but like to eat them anyway:
