In the coffee shop while talking with Bebe, Roz's hand goes from up near her mouth holding a piece of muffin to down on her lap between camera cuts.
Bebe's hair changes between scenes which are based a day apart. One day its classic Bebe, Day 2 at the zoo she has a perm and day 3 she is back to classic Bebe.
There is no zoo on Mercer Island.
