 // ===========================================================================
 // Leisure Suit Larry 5
+// In Miami the player can call the green card telephone number and get
+//  green card including limo at the same time in the English 1.000 PC release.
+// This results later in a broken game in case the player doesn't read
+//  the second telephone number for the actual limousine service, because
+//  in that case it's impossible for the player to get back to the airport.
+//
+// We disable the code, that is responsible to make the limo arrive.
+//
+// This bug was fixed in the European (dual language) versions of the game.
+//
+// Applies to at least: English PC floppy (1.000)
+// Responsible method: sPhone::changeState(40)
