A drinks waitress has complained that an elderly male customer slapped and kicked her and wrongly accused her of groping his groin in a Nakhon Sawan restaurant-bar.

Susita Rachakit, 20, filed her complaint with local police. She said that a male customer slapped her face while she was serving him beer, admitting that both of them were drunk.

The incident happened at a restaurant-bar early on Saturday morning.

The man had called her to his table and told her that he was ordering three bottles of beer.

She was serving his beer and talking to him. She said she had patted his belly in a friendly manner because he was a frequent customer. The man reacted by slapping her face and accusing her of groping his crotch.

Ms Susita denied this, and said that her mouth had bled after being hit.

Security camera footage showed the waitress moved away from the table and sat down nearby after being slapped. The man then walked over and kicked her to the floor, police said.

Police identified the man only as a 63-year-old retiree.
