A female tuk-tuk driver has been called in for an "attitude adjustment" session by Ayutthaya's Land Transport Office after she charged a South Korean celebrity 1,200 baht for a four-hour trip.

Il Hong Min, aka "Phi Hong", a well-known South Korean rapper and YouTuber, earlier shared an unpleasant experience during his trip to Ayutthaya on his "Oppa Hong" channel.

The trip is part of his travels through Thailand's 77 provinces.

The clip showed Hong and his friend being compelled to buy a four-hour tour on a local tuk-tuk vehicle at 1,200 baht.

The tuk-tuk driver, later identified as Somjit Tharangam, 59, even showed the tourist police logo and said the price was in line with the pricing standard approved by tourist police.

She also told them that Grab taxi services were illegal.

Hong and his friend reluctantly bought the tuk-tuk tour.

After reviewing the incident, officials said that the fare rate was set during the administration of the now-defunct National Council for Peace and Order.

However, the driver seemed to be forcing the passengers to buy the service against their will.

Ms Somjit and other fellow tuk-tuk drivers near the Ayutthaya railway station will be taken to the provincial land transport office for an "attitude adjustment" session to improve their behaviour towards their customers.

The police also told Ms Somjit to remove the tourist police logo that was put on the price rate tag.
