the proper way to walk

This has been bothering me for a while now. We drive on the right hand side in this country; therefore, when in a hallway or other area where the path is outlined or constricted, the logical side on which one should walk is the right hand side. Am I right?

I think about this because I work in a hospital, where there are several long corridors which through which I walk whenever I am there. I don't understand why someone would walk on the left side but some people do.

Also, a dumb ass who pushes and pulls those big carts that carry patient food trays pushed a cart into me once. He was on the right side but he wasn't looking where he was pushing for a moment and he pushed the damn cart right into me. He said he was sorry and I told him it was OK, but it really wasn't. In both the literal and figurative sense I was very sore. It gave me a nasty bruise on my left arm.
