A man is travelling over the wilderness in a hot air balloon

And he is lost so he lowers his balloon down to see if there is anyone around and lo and behold there is a man strolling on his own. The man lowers down further and shouts to the man, "Do you know where I am?" The man replies, "You are 30 miles above the ground in the wilderness." The first man stifles a grin and says, "Well, you must work in Information Technology." "I do," responds the second man, "But how did you know?" "Well the information you have told me is all factually correct but it is of no use to anyone," he responded. "The second man then says, "Well you must work in management." "I do," he responds, "But, how did you know?" "Well," he responds, "It says 'Welcome To Jamaica Have A Nice Day!"
