Since the 1990 spelling reforms we should be allowed to write "s'il vous plaît" with or without the little hat (circonflexe) on the "ï", but this exercise doesn't allow us the option of leaving it off (in either of the 2 sentences where it occurred).
Also (and this is even more minor) the "hint" gave us the wrong spelling of "Guinness", although it was then correct in the actual answer.
