Very sorry to hear you had that experience. But all for the greater good and all.
Interestingly I used Snip last year and was initially booked into Remuera clinic on a 1.5 month waiting list (They are that busy). I asked to be on the list of people to call in the event of a cancellation and decided to include Henderson as well to widen the changes.
Lo and behold Henderson called with a cancelled appointment 1 week later so I grabbed that. No issues afterwards but sure disconcerting to be sporting a raw hole in the sac for the next month or so.
