Communication. At work the better majority of the co workers and associates are those who speak spanish, and english. yet sometimes they switch back and forth whenever I pass the vicinity of them talking. Take this last saturday for instance; I come on shift, see two hispanic gentlemen from a distance talking in clear and distinctive english about setting up some drywall, yet, as soon as I almost pass them up side- by- side, it blips almost too fast in spanish as they continue past me. Now these were guys I didn't know from Adam, yet they felt the compulsion to do so as if I was an enemy. It doesn't stop with just passing by people in the aisles either. I've had to take orders from other people who can have very lucid conversations in english for the 1st couple of minutes, then,BANG!!right back into their own language. And I might add, so as not to generalize about just spanish, I've also witnessed, but not completely understood russian and polish, slovic, german, and quite possibly arabic. Why does this happen? I don't these people at all except for their orders.Thiskind of rudeness makes me wonder just exactly what it is about me that does not install any trust in them. Any similar cases/experiences?
