Buying Fish

I had this weird dream about 2 weeks ago. In that dream, 2 people were talking, there were parts of the dialogue that was so vivid in my mind, that I think I am gonna remember it for life...

The dialogue went like this:

A: What do you look for when you buy a fish?
B: the eyes, the gills, the flesh, blah, blah, blah*
A: If you spend such a long time choosing, wouldn't the fish be bad when you get home?

Sounds like something out of a Zen class huh?

*this was the part of the dialogue which I couldn't remember the details.
