Sometimes you choose a pet; other times, the pet chooses you.
This fish, who must have somehow sensed it was in a supermarket and not a pet store, is definitely in the latter category.
It makes the heroic leap from its tank into this guy’s shopping basket, only to be unceremoniously dumped back into the water. Unfortunate that it chose a man who was neither hungry nor lonely. Seems like it would have made a great pet—it already knew a trick!
Better luck next time.
