Piero Scartoni checks his math as he reviews a cafe’s weekly newspaper bill on October 19, 2023. The price of different Italian newspapers changes each day based on whether the paper contains additional sections or not. Scartoni has never used a calculator and adds customers' bills by hand and in his head. If people interrupt Scartoni as he is adding sums, he waits and resumes adding after their comment or question. He does not get angry.
"Sei vispo!" (you're spry) says one customer, when Scartoni arrives at the sum of his weekly newspaper subscription in his head before he does.
