The magic of golf

I go golfing all the time with my friends and we take it seriously and don't mess around or waste time, we hit our shots and walk on immediately. And yet the older generation of men and women (55-70) are far to proud to let us through even though we are held up by them on every tee. If we are on their tee at the same time and they Know they should let us through they simply blame it on the children in front although they are clearly not holding them up. Has anyone else had this happen, if so you'll know how frustrating it is and it can turn a 3 hour round into a 6 hour slog!
