To his admirers, such incidents confirm the relaxed, "no drama" Obama who perhaps realises the futility of another soundbite at this late stage in an ailing campaign, but for many disillusioned Democrats they also suggest a politician less than willing to go the extra mile any more.
On stage, there is a similar weariness, even in the stump speech.
In Providence, the presidential motorcade drops in at a well-known diner, so Obama can personally buy lunch and some of the cake that later gets used to bribe the press pool.
His staff like to refer to such moments as the "bear going on the loose", revelling in the photo opportunities that surprise encounters with the public can throw up, but these choreographed episodes are highly stylised, rarely straying outside a few brief pleasantries with customers.
Less visible are the fundraising opportunities, such a major feature of Obama's 2014 campaign schedule. On this trip, he hosts a reception at the woodland home of Bob Monks, the wealthy son of a former Republican Senate candidate of the same name.
Tickets for the 25 invited donors start at US$16,200 ($20,790), but the press is kept at bay in a neighbour's house while Secret Service guards prowl the large Cape Elizabeth estate.
These secretive fundraisers, typically held in stunning residential properties, have become a mainstay of the President's campaign efforts this year - his way of offering something to help the vulnerable Senate candidates who can't afford to be seen alongside him at rallies but are in desperate need of cash for television advertising.
Yet hints of the old Obama remain. "Hope is a better choice," Obama tells the audience in Maine. "Hope is what gives those soldiers in World War II the courage to storm a beach. Hope is what allows young people to march on behalf of women's rights, and workers' rights, and civil rights ..."
There are grounds for hope. Last year's bugbears - Obamacare, the lacklustre economy - are increasingly tamed. This year's challenges - Ebola, Isis (Islamic State) - may ultimately show the President's soundness of judgment. There is a chance the Democrats may not lose as heavily as the polls suggest.
