What was "recently"? Last night? Last week?

If it wasn't important enough to complain to the waitperson or manager, it isn't important enough to send a letter to corporate headquarters.

By the way, lobster isn't clear when it's cooked -- it's white, so I have no idea what you mean by that.

I also find it impossible to believe that it took "a few bites" to figure out that you were eating raw shellfish.
