Good one big guy.
The day I am having today, if someone gave me lip like that I would have a court appearance in the near future.
Note: It is not worth getting mad at someone for their driving, since they could be a stark raving lunatic with a weapon. Let it go... calmez vous.
15 minutes for a drive through Starbucks? Ouch.
I would love to explain that to the cops. "I don't know, sir, this crazy meth-head started ranting because I performed a simple and legal traffic manouvre. You might want to search their car, I saw the guy sucking on a glass pipe."
All actions are motivated, remember. I wonder what the dynamic duo's motivation was? Surely it was not a free coffee motive. Maybe they have a pasttime for long coffee lines. Maybe they took incorrect action when they saw your manouvre. The contents of the car were shifted around a bit and they were scared (through no fault of yours, even if you didn't see it) and the subsequent adrenaline dump made her get out of the car. Don't underestimate adrenaline. The Fight/Flight thing is powerful, and they couldn't flight without bypassing their coffee run. My opinion only.
I never appologize for things in traffic, even when it is my fault. An appology is an admission of guilt in court, and as such you took full responsibility by uttering those words. Try to refrain in the future.
In an accident, ask "Is everyone okay?" instead of saying "Im sorry." Your insuance provider will thank you for it.
