That burger in Iron Man definitely should have been In-n-Out to be believable, no 00s hip LA playboy billionaire would have settled for anything less and Burger King in there was like fingernails on a chalkboard.
Here's how the scene should have played:
Tony Stark is late for the press conference because there was a long line at the In-n-Out on the way from the airport, even though there were only a couple of cars in line at the BK across the street, BK was not an option!
Yeah at about $2 more per patty in a good location. I haven't seen one that's less that $4, but I don't spend anymore time than I have to in the south.
