I would imagine that Clint is on a first name basis with a lot of New York’s emergency responders.
Hurt and in the back of an ambulance?
The driver is like “Clint Barton is that you again?"
"Yeah, it’s me, you know I like helping people every way I can. Like letting you earn your paycheck, Barry."
Need police assistance?
"Hey, Doris, yeah it’s Clint, I need some help. Oh yeah, Lucky is fine. How’s the husband? Oh that cheating bastard."
Caught dangling from a telephone wire because the jump to the other roof was farther than expected?
"Honestly, Karl, I don’t do this on purpose. No, it isn’t an excuse to get to climb down the engine ladder or play in the fire truck.”
Mistaken for a burglar for trying to help some little old lady and sitting in the back of police cruiser?
“You aren’t going to tell Doris about this are you Meredith?”
