Best Informant

An officer was sitting at a diner have some coffee late one night when a group of known drug dealers came in and sat down on the other side of the establishment.
 

One of them in particular was constantly cursing.  Every other word was a swear word.

The man gets up to go to the bathroom and the officer follows him.  "Hey man, can you tone down the cursing a little bit?  It's pretty obnoxious." 
 

Well the man lets the officer have it.  Curses him up one side and down the other then walks out the bathroom to rejoin his dope dealing friends. 
 


The officer calls the waitress over to him and asks for the mans bill.  He further instructs her to tell the man, in front of his friends, that the cop paid for his bill.
 


As the officer heads for the door, the man smirks, "that's what I thought, pig."
 



The officer turns to the man, "Its the least I can do for my best informant."
 


Gotcha!
