First 9 holes were amazing the course was playing brilliant, and we were behid a 2 ball, a four ball and play was fairly quick. Then the 4 caught a 2 ball up and play just stopped, to the extent the 2 ball in front of us walked off after 9 holes. We then caught the 4 ball up and had possibly a 5 minute to 10 minute wait on each T after the 11th. This obviously spoilt the rhythm and enjoyment to the point we walked off after the 15th
