Ok, I know you expect us to be guessing how far you'll have to walk before someone will buy you lunch.
Might be a fair distance since it's only the top hatted American bankers who smoke cigars.
Right, took a bit to puzzle it out.
You are expecting someone to pony up for the chow in hopes the Bank (yours) will loan him seed money.
Figuring that you"ll be at your stately bankers pace.....40 puffs = 19 feet...
you should be putting the feed bag on after twenty feet, that's my guess.
