Write about: the barter system.
Good lord, the internet connection here is slow. I know it's never good, but it's been downright painful tonight. I just spent almost an hour (on and off) trying to get this far in the process (as in loading up my post template).

"That's how much it costs to ride the bus, sir."
"I don't carry change," Henri replied, puffing cigarette smoke out the left side of his mouth. "Too noisy."
"Too...? Listen, sir, I cannot allow you to board this vehicle without payment."
"Fine. Whatever." Henri stuffed his hand into his breast pocket and pulled out a pack of smokes that contained, at a generous estimate, a quarter of its original contents. "Here you go."
"What... sir, you cannot pay your fare with cigarettes. Ignoring the fact that I do not smoke, it is entirely inappropriate. What do you think this is, prison?"
"No, of course not my simple fellow." Henri smiled sweetly, gave the man a firm pat on the cheek. "If this were prison, you'd be the one offering me cigarettes. Now get to driving - I have an important client waiting for me across town."
