(at around 15 mins) Teri comes back with the oil asked by Rick. He is working on the motorcycle, and wears protective glasses. While Teri grabs him to the chair, we see he's removing the glasses and holds them in his left hand. A second later, in the close shot, the glasses have disappeared.
The goof item below may give away important plot points.
After Rick is killed at the club, a janitor is mopping up the blood spot with the body outline fresh on the floor. At first the wet mop is shown up close sploshing onto the blood spot and smearing it around, then the camera zooms back and you can see the janitor pushing a now-dry mop around the edges of the blood spot (with no smeared edges) but never touching the spot.
When Teri first delivers the bike to Bob Jenkins, a woman rides the bike to a stop and firmly plants her brown leather cowboy boots flat on the ground. Bob's face is then shown and the camera switches back to the bike, which is sitting on its kick stand, and the woman has on white boots, and is much shorter as she is on tiptoes. After Bob is killed, the taller brown-booted woman rides the bike away.
