Some people easily get angry over minor things.

A 73-year-old man who patted the head of a little girl dining with her parents at a shopping mall food court in Singapore angered her overprotective father.

The surveillance camera at the food court of Roxy Square mall caught the 40-year-old father confronting the old man and shoving him to the ground last 15 August, Channel News Asia reported.

The senior, Yeo Song Khoon, later told the local media outlet 8world that he patted the girl’s head as he found her “very adorable.”

The footage of the incident also showed the girl’s father calming down and apologizing to Yeo.

Although Yeo and the father amicably settled the matter, the old man was apparently injured when he fell to the ground, so his family reported the incident to the police and appealed to the public through social media to help identify the man who shoved him.

Meanwhile, the sales clerks at an electronic store in Russia include an aggressive one that attracts customers with its unique appearance.

A CCTV camera at Volga Electronics in Saratov caught the made-in-China humanoid robot reacting when a male patron entered and tried to shake its hand, the New York Post (NYP) reported.

The 4-foot-tall automaton is shown in a video clip of the encounter, snubbing the patron, who then gives it a playful shove.

The footage shows the robot reacting by making a kung-fu stance and then unleashing a series of Bruce Lee-style kicks and punches at the customer, who fortunately dodges the surprise attack.

Two human clerks then appear in the video and try to restrain the robot, which continues to swing its fist and kick at the customer, who is not hit.

It was unclear if the robot’s antics were just for show, but reactions to the video of the kung-fu spectacle posted on social media seemed to alarm one commenter.

“These f–king bots are going to kill us for sure!!!” read the comment, according to NYP.
