SoCal, I didn't pass my RT until 19 years after I got my PPL!!
It wasn't a legal requirement to have one in the '80s and it wasn't until I came back to flying later on that I had to do it.
In this situation I normally say to the A/G: "G-xxxx request circuit traffic" which normally gets me a quick run down of who is doing what, this is especially useful at airfields where you need to backtrack
