should not the Thai green curry and avocado shrimp at least a nibble of shrimp? After paying extra to have shrimp instead of beef, chicken or pork, you would think they would put some shrimp into the stuff instead of just veggies. I haven't found any

I agree that it,was likely a mistake. They are normally generous with their meat and seafood. They would definitely have fixed it had they been made aware.

Seems like they just made a mistake, and I would have asked about it/mentioned something to the waitress. They're usually pretty good about fixing stuff if doesn't come out like it's supposed to.
