Withnail & I (1987)

Factual error: When they are driving back home from the holiday cottage you can clearly see an M25 sign in the background. The M25 didn't exist in the 60s.

Withnail: I've some extremely distressing news.
Marwood: I don't want to hear it. I don't want to hear anything. Oh God, it's a nightmare, I tell you, it's a nightmare.
Withnail: We just ran out of wine. What are we gonna do about it?
Marwood: I don't know, I don't know. Oh God, I don't feel good. My thumbs have gone weird! I'm in the middle of a bloody overdose! Oh God. My heart's beating like a fucked clock! I feel dreadful, I feel really dreadful!
Withnail: So do I, so does everybody. Look at my tongue, it's wearing a yellow sock. Sit down for Christ's sake, what's the matter with you? Eat some sugar.

Trivia: The bottle of lighter fluid Withnail drinks had been filled with water throughout rehearsals, but for the actual take was filled with vinegar, unbeknownst to Richard E. Grant, who plays Withnail. The director made the switch to get a good reaction from him.

Question: Why doesn't Maroowd want Withnail accompanying him to the train station? I thought they were supposed to be friends?
