I worked for TDCJ for a couple years, there were plenty of strange and sometimes salacious scandals. They often failed to make the news. That being said, no CO that I knew wanted inmates to know where they live. I only know of one case of a prison officer taking an inmate to their own home, and that was rumored to have been for sex. That doesn't mean a thing didn't happen though. CO's and other prison folks are very insular, and don't usually discuss things outside their tribe (well, not current affairs anyway).

There is limited on-unit housing for officers, and inmates are responsible for maintenance of those.

It is not unheard of for inmate work-crew supervisors (officers) to buy their workers a hamburger or take-out meal; this is usually during or after a shift of unusual duration or a situation that deserves a little recognition.

There are special cases. My grandfather, a county sheriff, was granted custody of a TDCJ inmate by the director. The inmate worked as a porter in the county jail, and occasionally was my babysitter for short periods of time. This was in the '70's.
