I have an interesting take on this following my experience playin gat the Bangalore Golf Club in southern India ... I was matched up with 2 local players and the custom is that you take a break after 9 holes for lunch or a snack, depending on the time of day. However this is more than a snack bar stop, this is an opportunity to catch up with friends, network & so on. The 10th tee is worryingly close to the dining area (think 1st tee at Merion East Course!) and you siomply re-start your round at an appropriate time. It was all very relaxed. As an aside, Bangalore Golf Club provided a wonderful experience & welcome, I recommend their hospitality & course highly!
