The right stuff.

 Whatever the job requires, he's ready.

 Just for the record, his name is Webster.

The working man.

A billion here, a billion there.

The big tipper.

 My what big tips you have. What tipped you off?

The better to steal.

Wash your hands frequently.

 Proving that there is no safe distance with some people.

Keep at arm's length.
