The plug from the table going into the power strip looks to be a european style, the background is clean and litter free and, although drinking the three guys appear to be fairly sober. I suspect that they are all college students and if I'm right, european college students, which typically are more intelligent than american college students, so either the whole set up is a set up or there's more to it than any of the pictures might indicate.
Had this occurred in the U.S., the three would be drunk, vomiting, there would be equally drunk females present and the background would be littered with garbage and broken bottles. Oh and that orange extension cord would actually be plugged in somewhere and they would all have been killed. Of course, it wouldn't have been their fault but that of the college. After all, they're just kids, they didn't know any better.
