Turning off Burst Mode in iPhone 6 Camera

Assuming I am not missing something (would not be the first time), I assume that there is no way to disable the Burst Mode in the iPhone 6 camera?

My reason is that we were out to dinner and I asked the waiter to take a picture of the four of us. I turned the flash on the camera to ON (as the restaurant was dim but was not sure if the flash would go off if on AUTO) and handed him the camera. What I guess happened is instead of tapping the shutter button, he held it - probably waiting for the flash to go off - and ended up taking three separate Bursts of approximately 45 photos. None of which were even reasonably sharp because there was not a lot of light and the flash did not go off. (BYW my friends wife also had an iPhone 6 and got the same basic results.)

Now (and yes, I did leave Feedback) there should be a way to either disable Burst Mode or at least it should automatically be disabled when you turn the flash to ON (as the flash does not work in Burst mode anyway). I went through everything I could find in Settings, but saw nothing related to the Camera itself. (I guess if I would have used another camera app, this "problem" would not have occurred, but it never dawned on me.)

Thanks for any suggestions.
