A customer refused to pay the 21 baht VAT on the bill at a ramen restaurant in a Bangkok petrol station and tried to storm out without paying - only to be stopped by other diners.

The argument was recorded on video by one of the other customers, who posted it on TikTok. 

It happened on June 8 at a PTT station on Sukasawat Road, according to TikTok user @moveforwardlandslide. The customer, a woman, argued loudly with the staff, claiming she was being overcharged and refusing to pay the bill.

The argument was about the inclusion of 7% VAT in the price of her meal. The angry customer refused to acknowledge the VAT included in the price, insisting her bill should reflect the actual price of the food and drink she had. The bill for the food was 321 baht, a price that included the 21 baht in VAT on a 300 baht meal.

According to the TikTok user, the customer refused to listen to explanations by the restaurant staff, demanding they recalculate the bill as if it were a purchase at a 7-Eleven store, which she claimed does not charge VAT in the same way. 

There were only two women staff members working, and they appeared distressed by the situation, the TikTok post said.

As the angry customer attempted to leave without paying, the TikTok user and another patron blocked her exit, insisting she settle her bill. Eventually, the customer paid up, but continued to argue during the transaction.
