For the record, I've done two BFR, including one at Rainbow Air and on neither was I really asked any questions, at least not in the formal sense. There was a bit of pointing at the map and saying "Do you know what that magenta line means?" and me saying "Urm, I've read about it but I can't recall" and them explaining it. It was one hour of ground instruction and one hour of flying around doing a few stalls, slow flight, etc. Most definitely not a test - the instructor demonstrated various things to me first.
Rainbow Air's checkout is fairly thorough and they do give you a sheet of written questions, but they are very easy generally, plus you can take it away with you (I did mine overnight) plus you can use the handbook plus I left a few blank and said I don't know and the instructor and I filled them in together.
All in all, neither of these things are anything to worry about. That, OBK, is probably why they've not mentioned any of it.
