The 38-year-old, identified as Tao Hsiao, had been shopping with his girlfriend at the Golden Eagle International Shopping Center in Xuzhou, China, when she asked to check out one last shoe store.
Having been inside the mall for five hours, Tao had reached his limit, and reportedly insisted that they leave immediately.
"He told her she already had enough shoes, more shoes that she could wear in a lifetime and it was pointless buying any more," an eyewitness was quoted as saying. "She started shouting at him accusing him of being a skinflint and of spoiling Christmas, it was a really heated argument."
A spokesman for the shopping center says no one below was injured in December 7 incident, and that the man died instantly upon impact.
"This is a tragic incident, but this time of year can be very stressful for many people," the spokesman said.
