Mason Storm: So, how come you're not watching the Oscars tonight?
Counterman: The Oscars?
Mason Storm: Yeah, the Oscars.
Counterman: I hate the Oscars.
Mason Storm: You're not having a good time, huh?
Counterman: I mean, who needs the goddamn movies anyway? I got a show in here every single night.
Mason Storm: Yeah?
Counterman: You've got horror, sex, freaks, violence. I don't got to pay no four bucks either.
Felicia Storm: If people knew how sweet you are, they'd never be scared of you... I'm not scared of you.
Mason Storm: Maybe you should be.
Felicia Storm: There's blood on your shirt.
Mason Storm: It's not my blood, so you don't have to worry, do you?
Senator Vernon Trent: You can take that to the bank.
Mason Storm: I'm gonna take you to the bank, Senator Trent. To the blood bank.
Mason Storm: What year is it?
Andy Stewart: Try not to talk.
Mason Storm: What year is it?
Andy Stewart: It's 1990.
Mason Storm: This is for my wife. Fuck you and die.
Answer: He survived the first attempt of his family's murder. There's no telling what he saw or heard. As for the masks, the bad guys were taking no chances, security cameras, cell phones and the unexpected eyewitness.
Cell phones? I don't recall seeing a cell phone in the entire movie. It was all landline phones. Cell phones didn't really start to get used until around the mid-90s (a few years later).
