Continuity mistake: When Hank is standing between the ATM and the pumps at the gas station, the shadow cast by the roof over the pumps shifts between shots. The shot from away, taken next to the pole with the Indian logo was taken earlier in the day, casting a long shadow. The other shots have a higher sun which has moved by several hours.
Visible crew/equipment: Skyler is making copies and the scene starts with a shot looking down into the copier (the Green Light). When the shot lightens a bit as the copier continues, you can see the camera lens. This makes sense because the camera is sitting directly on the copier looking down.
