Interesting we're talking about one of the oldest, most fundamental rules of golf which is let faster players play through, and people (not all) act like the single is the plague. It's to me, with over 20 years in the business, mystifying. The idea, however logical or simple, seems to rear it's ugly head throughout the golfing season and is something I'm convinced will never, ever, go away. That being said, unfortunate as it is, you have to come to expect the reaction if you're a single or in a faster group. One's sense of entitlement is a tricky thing.
