Visible crew/equipment: When Brad and Stacey pull up in front of the bowling alley and Stacy opens her car door, several crew members can be seen reflected in her car door's window. (01:05:50)
Continuity mistake: When Mike is trying to get Mark to ask Stacey out, there is a shot of her behind the counter and Stacey's hair is pulled back on the sides in french braids with ribbons on the ends. Then when Mark approaches Stacey, her hair is pulled back in a clip. The first shot of Stacey with the braid, is actually cut from a scene later in the film, when Mark and Stacey talk at the counter. (00:27:35 - 00:28:20)
Answer: This could be considered a mistake. Some people say the pizza cost $1.05, and he gave her $1.10, with 5 cents back. But if you watch the register, she rings up $1.10 before he hands her the money and then it shows $0.05. It seems this part wasn't in the script, so was added as filler and some of the sequence is slightly off.
