> l. I was told that if you arrive at a B&B after 4pm, you can ask for what is known as a walk-in rate.

I just checked with my sister who owns a B&B in Nova Scotia and she is unaware of this practice there. She often gives discounts to honeymoon couples or upgrades but not a discount because she has availability and it is late. It might be something they do in BB heavy areas like Bar Harbor, Maine?
