Recently I was dining in a seafood restaurant and was ordering some shrimp dishes. I asked the waitress the size of the shrimp. She replied nice size (a non answer). One of the people at the table commented that size shouldn't matter as it was all you can eat. I pointed out that since some of the shrimp dishes were breaded, it could make a big difference. I didn't want to bite into mostly breading and not experience the taste and texture of the shrimp. Depending on how you are preparing certain recipes size definitely matters.
