Pass the salt!!

A group of screaming  people were banging on Bob's door demanding to be let in.  An angry  roaring Grrr, was turning the corner in hot pursuit of them. 
Sticking his head out the window; Bob said: "Whata you want?"
"You have to let us in." the leader commanded.
 "An angry savage T-Rex is after us."
"Why?" asked Bob. "Grrr usually does not bother anyone who does not bother him." 
"You do not understand. We are from the national food dept and have come to inspect, to require, to insure that creatures and people only eat what the Government allows them to eat. Food like soy, that  has a low carbon food print and nurtures the environment. That brute of a  T-Rex was drinking ..Gasp..root beer and eating burgers.
So of course, we ordered him to stop; pointed out the error of his..tried to educate him..we issued a fine and  and attempted to remove the offending food and drink when he went....he started to eat us!!!.  You must do something."
'You are right!" said Bob.
"Hey, pal, you may need this" Bob said...Tossing Grrr some salt !!!!!!!!!!! :
