If he has no way to get to the interview, lift all the cushions on the couch and find all the change. Take that wonderful thing that all libs love, public transportation.
You know, when I lived in Lincoln I really hated parking meters.
And so even though I had money, to make a "protest" out of it, since the parking meters weren't finely calibrated, I used small coinage from the Seychelles, the Bahamas, Turkey, Brazil, Mauritius, the Ivory Coast, whatnot.
Automotive and street taxes were (are) pretty high in Lincoln.
But I also happened to notice that if one's looking for change, the base of parking meters is a great place to find it. Apparently many times people start putting a coin into the meter, and drop the coin, and rather than bending down to pick it up, they just put in another coin.
I'll bet the crooked tale primitive could find bus fare simply by scraping the superficial dirt at the base of, oh, about half a dozen, parking meters.
