Larger Fish

"Two men were in a restaurant and ordered fish. The waiter brought a dish with two fish, one larger than the other.
One of the men said to the other, "Please help yourself. "
The other one said "Okay", and helped himself to the larger fish.
After a tense silence, the first one said, "really, now, if you had offered me the first choice, I would have taken the smaller fish!"
The other one replied,"What are you complaining for; you have it, don't you?"
