When in the cafe Stewart confronts Eddie he offers to buy a fresh cup of coffee, whilst at the counter he looks back to Eddie where his own cup is on his side of the table, when he looks back and Eddie is gone the cup has moved to Eddie's side of the table.
In the casino, Stewart leaves a note on a matchbox for Jason to find. In closeup, the note reads 'recognised me'. But Stewart, being American, would have spelled the word as 'recognized'.
Also, there's a mistake in continuity with Jason wearing/not wearing sunglasses as he enters and exits the bathroom.
