Had this 'discussion' with a few ppl via Twitter last night that were saying how Phil should be pissed etc.
A. Phil didn't have to let Rory play up
B. Rory could've simply said it's too dark
The restart was for 9am so it's 12 hours were talking about here and not that big a deal.
Golf is a different game then all other sports (thankfully) where u don't try to blow in a competitors ear, hit him in the nuts and poke his eyes at bottom of pile, or take a dive.
You help your opponent find their ball if they need you. U may sometimes let them know a rule before it costs them, and yes you let them play with you if darkness is about to stop play
Just my .02
