A small company valiantly struggles to survive under the respectful yet probing camera of Claire Simon in “At All Costs.” As the docu opens, founder and manager Jihad is off to see his banker. The lack of ready cash to pay his loyal employees, wholesale produce providers and a whole range of other creditors, including the tax-gobbling French government, is omnipresent. From a staff of 14, Jihad is down to three cooks, one delivery driver and a secretary in less than six months. The good-natured pluck of the remaining employees is at the heart of the film. Subterfuges for putting up a brave united front include scheduling food orders from a coin-operated pay phone when the office phone is cut off for nonpayment.
