NO SPOILERS
I do love all the subtle clues, foreshadowing and character introductions they threw in the first scene. First, they talk about random stuff, which mostly involves Mr. Brown and Mr. Blue, meaning they’re not important considering they get killed immediately after. Mr. White taking away his notebook in a joking manner shows their friendship. Mr. Blonde kiddingly suggesting to shoot Mr. White shows he’s a psychopath who enjoys killing. Next, they debate whether they should tip waitresses or not, as they’re in a situation to give which is ironic for robbers like them as they usually take instead. Mr. Pink is the only one who doesn’t wanna give a tip, showing he thinks for himself, which is why he’s the last man standing. Mr. White says he should tip the waitresses by pointing out that they all count on their tips to live, showing that despite his tough facade, he has a soft spot which leads to his demise. Mr. Orange, who was the most silent during the conversation, agrees with Mr. Pink because he tries to fit in. When Joe asks who didn’t tip, Mr. Orange rats him out, showing he’s the mole.
