I always had done tongs wiggle jiggle thingy and works for majority of my snakes.
I have that one snake that keeps coiling and then not eating it. Tried feeding smaller, less frequent etc. etc. same crap.

I now have a new snake that didn't strike when I did zombie dance. But I left the darn thing in there and 1 hour later rat gone.

I now remember when i first got the one that coil and doesn't eat it, there was once I did jiggle it didn't strike and I left it in there in frustration and 2 hours later rat gone too.

I had kept on wiggle jiggle for her since that's what you're supposed to do with f/t. Tonight, again no eat. I wonder if it is better for me to just throw the darn F/t rat in there leave over night every time?
