Lloyd the Bartender....
Many people think that the scene between Jack & Lloyd at the bar is a plot hole or a mistake in the movie. This is the scene where Jack stumbles into a deserted barroom & then Lloyd suddenly appears.
Some people are of the opinion that it was a "goof" when Lloyd & the rest of the crowd disappeared when Wendy came running in to find Jack sitting down at the bar. What goof? They just chose not to manifest themselves to Wendy quite yet. Meaning maybe they all did disappear but it was no mistake. Again they chose not to make their presence known quite yet. Wendy as we see got plenty of that later on.
The one "goof" that was in this scene was that Jack asked for a bourbon & Lloyd poured his drink from a Jack Daniels bottle which is whiskey. So if anything that's the "goof".
