Library Walkabout

Does anyone else feel uncomfortable about walking patrons to the stacks? I don't mean in a security sense--I mean in the sense of finding a good walking speed and position in relation to the patron.

I tend to walk rather briskly, particularly in the stacks, and find that many times patrons just meander behind me. But if I slow down to their pace, they often slow even further--they usually seem more comfortable following, rather than walking side-by-side. This can make me self-conscious, and as a result, I tend to be acutely aware of my walking while in the stacks.

Am I just overthinking this? Or is the perfection of walking speed/position something imperative to good user service?
