Hall of Famer
If I'd booked a tee time at a course, paid my green fee then after waiting on the tee due to the course being busy and then got told a members foursome comp was going to extra holes and I had to delay my tee time even more I wouldn't return to that course.
I know comps have priority but going to extra holes is just tough luck and you should plan for that.
From funding out you're opponents how long did you have to play the match by?
But as it was a) foursomes and so would move quickly and b) going to a few extra holes at most it isn't as if this is really going to interrupt your day out that much. If I'd been in the same position I'd have let them go. Hit a few putts and they'd have been gone time you got back to your bag and problem over. If you can't wait an extra ten minutes I wouldn't book a tee time at busy periods.
