Hello SherlockHolmes,
Welcome to the forum!
I felt drawn to your post even though I do not really have an answer to your question so I'm bumping this up in case someone may read and be of assistance to you in any way.
On another note, I do believe that we do have the answer/s we seek though the revelation may take time...
It would perhaps be good to establish a friendship with the waiter guy, this way you can explore what connection you may have with each other.
Your story seems very interesting and I wish you all the best!
Blessings to you,
