I was visiting a friend in Redwood City,CA in 2001, where there is a huge Mexican population, which has probably exceeded the caucasian population by now. Hehe, I remember taking my laundry to the laundermat one Saturday morning - I was the only white guy in there, all others were Mex, but that was OK.
From the balcony of my hotel room, I could see another hotel being built - just a small one, 2-3 storeys. The building workers were all Mex, and by heck they DID work hard! They were putting the roof on when I was there, and they kept right on the job and never stopped. It was a pleasure to watch them, their radio tuned to an Hispanic station, cheerfully hammering in tile after tile.
In Britain, there would have been a couple of tea breaks and a cigarette break in the time I was watching.
