The poem is a tiny riddle about travelling cheaply. The speaker says "we tell money / how to serve us without money," which sounds like a contradiction: how can money serve us when we aren't spending any? The answer seems to be that a budget traveller gives money orders, bossing it around with a strict plan, so it stretches as far as it can.
The last two lines bring the idea down to earth. All the traveller needs from "any given road" is "several businesses and a bed": a few places to buy food or supplies, and somewhere to sleep. That's a modest, almost stripped-down list of wants.
The tone is dry and a little wry. The speaker sounds practical, even slightly proud of making do with so little, yet there's a hint of loneliness in how bare the road is. Judging by the wording, the poem suggests that travel doesn't need much, though what it leaves out, such as scenery or company, quietly hangs in the silence.
