Continuity mistake: As Buffy is being trained at the register, the receipt at the top of the register switches in every shot. (00:07:45)
Continuity mistake: Timothy is wearing disposable gloves as he is training Buffy at the grill, but in the shot when he puts the raw patties on the grill, he is barehanded. (00:16:15)
Continuity mistake: When Buffy is assigned to the grill, as Timothy explains the process he's wearing a short-sleeved orange/white stripe uniform. In the close-up, when he places the second patty on the grill, Timothy is wearing a 3/4 sleeve, dark blue shirt. (00:17:15)
Continuity mistake: When Timothy shows Buffy how to use the grill, there is a wood-handled grill press, and another tool, right in front of the button panel. However, after he says, "It eliminates variation," in the close-up as he presses the button, both tools as well as the transparent plastic glove he wears have all vanished. (Another mistake notes a different close-up with a disappearing glove.) (00:17:25)
Continuity mistake: The finger changes position in Buffy's hand as she picks it up. (00:23:35)
Continuity mistake: New boss Lorraine unfolds her arms twice. (00:39:05)
Continuity mistake: When Buffy's friends come visit her at work, WIllow is playing with some straws in a styrofoam cup next to the register which disappears a few shots later.
Continuity mistake: When Manny stamps Buffy's card in the time clock, he hands the time card to her with his right hand, but in the next shot facing Buffy, Manny hands the card to Buffy with his left hand.
Continuity mistake: When Buffy is being offered the 'doublemeat medley' burger by her boss, the burger looks different in close up than in the long shots. In the close shot, the burger looks overall bigger, more filling is visible and there is more lettuce sticking out.
Continuity mistake: In the scenes where Buffy is being taught how to cook the burgers, the guy that is showing her has safety gloves on. In the close-up of the guy turning the burgers and pressing the buttons, the gloves are gone, and in the next shot, his gloves are back on.
Chosen answer: Angel is saying that he is still jealous and Buffy recognizes that this is his way of saying he wishes that they could be together. That is why they both smile.
