What the heck? Was the chef trying to get high?
He was probably trying to make a point about a stupid rule by proving that putting a small toad in his mouth is perfectly safe, thus rendering the burro-crat's "THIS COULD KILL SOMEBODY" point moot.
There are stupid rules out there with idiot burro-crats to try to enforce them.
And fed-up people will do a lot to prove a point before they finally get fed up enough to just 'shoot the barstid to shut him up'
