I played with a couple random guys in their 50s this week, one of whom made a couple pretty racist comments (I'm white and look pretty generically white).
On a slippery downhill putt I hit the ball quite softly but still ran it well past the hole. This guy said "That thing was runnin like a brotha with a check to cash."
We were also behind this ultra slow 4some of old guys some of whom could barely move and made no attempt to counteract that by being conscious of pace and fell way behind. We were complaining to each other about it here and there, and once this same guy took the opportunity to launch into a story about how he once got stuck behind a set of groups of Asian tourists who came in together on a bus and took tons of pictures and generally just played incredibly slowly. His intro line to this story was, "One time, there was this busload of ornamentals, ..."
Both times I just gave him a sort of grimace and didn't respond as they were said early and mid round, respectively, and I didn't feel like making a scene and then finishing the round with the guy and his buddy. How would you guys respond?
