To get back to the point of this thread, i.e., the loss of work because of a perceived threat to someone's income.
Prior to "the vote" was the collapse of the financial markets, which happens on a regular basis. Many of us lost jobs to the fear that people would lose the incomes, savings, houses, hamsters, dogs, cats, kids, in-laws (well to be fair most only wish they could lose these!), etc, etc....
People will always perceive some sort of threat when they live on fixed incomes and need to watch their pennies.
My wife and I are talking about reducing the scope of a renovation because we're afraid of unforeseen expenses biting us on the butts! Bet the contractor is going to be telling this tail of woe to all his buds.
Be understanding with them and throw them a bone so they'll come back when the sky doesn't fall. Guarantee the price say for the next 2 mths. This way they'll feel confident in you and if nothing has happened to the medicare over that period they'll be motivated to do the work for FEAR that the price is going to go up!
