I know what your saying they make LIARS of us, and we feel like idiots, 
Cute story, with the tie. Vet probably figured, DANG, when was the last time that dragon got feed, hahahhahaha (kidding) 
Happened to me when I took one of my very old sheep dogs to the vet. Needed some dental work.
I said while he's here, might as well cut his nails, as lately hes very GRUMPY, when I do it.
I went on for 5 minutes about how he growled low at me now, shows his DISPLEASURE with the whole ordeal, blah blah.....
That sucker sat there, like a big sweet heart, never moved as they cut each nail. LOL
I could have BOOTED EM!!!

Any way back to dragons, HOPFULLY, Bennets guy will be fine!
