When Ollie and Stan park their trailer in the hills and decide to have beans and coffee for dinner, Ollie sets up a table and spreads a tablecloth, checkered with a wide lighter-colored stripe on two edges. Ollie spreads the cloth with the lighter-colored edges on the end of the table toward the camera. Once their lady visitor arrives, the stripes at the ends of the table aren't seen anymore, only the checkered pattern.
Ollie's tie keeps changing in length.
When Stan fills the bathtub and the water is steaming hot; in the next shot from outside the bathroom, all the steam is gone.
In the trailer, a plate of beans flies off the table just before Ollie's fist comes down.
