What is the doctrine of ordering French fries at the dock?

Highly opportunistic. Seagulls eat whatever they see. Fish, wild fruits, rabbits, birds' eggs and, of course, French fries on the dock will all be its delicious meals, and no opportunity will be given up or missed. This is highly opportunistic. The stalk "seagulls go to the dock to order French fries" comes from an expression pack. In the picture, two seagulls are discussing the meaning of seagull life. One of them asked the other, but the other replied, "Go to the dock to order French fries." He was bent on going to the dock to order French fries. This sharp contrast is very gratifying.
