I wonder what's so unusual about that where The Onion even cared.
That's just two locals being friendly.
Very common actually. I've had contractors come to my house an ask who installed my pool fence, or who poured my patio.
And a lot of guys will identify well known landmarks where they've worked to support that they do good work. "Oh, you ever see that big house on the corner of blah-blah street? I did the deck/porch/paint/whatever for that." ... "Oh, great!"
