I asked my lunch companion, "Has anyone been knocked off here?"

"You want to track down our lunch companions, make sure they're okay?"

I was looking for a lunch companion and look who shows up.

And, unfortunately for my lunch companion, I learned nothing that would give me greater confidence in her professional services.

His lunch companion was the same age my friend and I had been when we cavorted around as teenagers.

I don't have anything to offer my lunch companions anymore, so I sit by myself.

My lunch companion, of course, was not my father at all.

Fred was the best friend, best partner and best lunch companion.

I asked my lunch companion if he'd be finishing off with that pie.

He answered, but cut the conversation short, apparently not wishing to be rude to his lunch companion.
