Continuity mistake: In the baseball game, when Zack runs into Vince, the ball flies away from them as they fall on the ground. In the next shot, it is on Zack's glove. (01:19:45)
Continuity mistake: When Zach is getting ready for his date with Amy, Zack's beard length changes from a "five o'clock shadow", to a full beard, back to a "five o'clock shadow", between three shots.
Revealing mistake: Jorge misses scanning the barcode on the tire by several inches at the end of the competition, but it rings up anyway.
Continuity mistake: During the scene when Zack sneaks into the cashier's lounge, his buddies are spying on him with a pirate telescope. However when Iqbal hands it to Russell to take a look, the shot is now zoomed in to Zack swiping the card in the slot. This would be impossible as the telescope is fixed to one focal point and was already fully extended for the first shot.
Continuity mistake: During the checkstand competition Jorge gets tangled in Vince's scanner cord and backflips onto his face. A split second shot change and he's back on his feet pushing the cord out of his way. Then finally in the next shot he his shown just coming to his feet.
Factual error: The kind of CCD bar code scanners used by the cashiers in the movie have a maximum read range of just a few inches (or less). Given this limitation, it would be impossible for Vince to scan the item from as far away as he did, at the beginning of the movie.
Revealing mistake: Even though the movie is set in the fictional "Super Club" store you can tell it was filmed at a Costco. Some things that give this away include: Kirkland (Costco exclusive brand) products are visible in many scenes, when Dane Cook and Jessica Simpson are talking early in the movie you can see part of the word "Costco" and finally most of the signs and layouts are EXACTLY like a Costco.
Continuity mistake: In the scene where Semi is being questioned about the permanent marker, the chain on his neck changes position in every shot.
Continuity mistake: At Iqbal's son's birthday party when all the guys are around the table playing cards, Russel has his hands free when he talks to Zach about employee of the month. In the next shot, he is holding a beer in his right hand and asks Lon to pass the chips, in the next shot it is back on the table where he picks it up.
Continuity mistake: During the baseball game, the shot right before Zack finally leaves the store to come play shows the scoreboard at a 0-0 game in the first inning. The scoreboard shot before that one just showed the score as being 2-8.
Continuity mistake: While Zack speaks with Amy at the organic food store there is a worker behind them who passes by several times, and a guy in red who does the same thing.
Continuity mistake: When Russell gets Amy info, the folder flips side between shots.
Continuity mistake: In the scene in the beginning when Zack is in the clubhouse there are beer cans on the floor. When he gets up to look out at Simpson they're gone.
Continuity mistake: When Zack wins his first gold star, it's on day 12 and Vince has 11. Later we see Vince has earned 5 more stars (which would put him at 16), but Zack's first star is now on day 11 and Vince only has 10 stars up to that point.
Continuity mistake: When Vince goes in for a kiss, Amy tilts back and when he kisses her, she tilts (recoils) back even more. In the next shot she's back to her original position.
