The man ate in the sushi chain store Genki Sushi at East Point City, Tseung Kwan O at around noon on Saturday (October 2). Halfway through the meal, the man shared his visit to the “Hong Kong Sushi Sashimi Concern Group” on Facebook, where people share their dining experiences.

But netizens spotted that there was a receipt next to the dishes, which carried a QR code which diners can scan to place orders.

They ended up placing over 140 orders for the man within nine minutes, which led to a bill of HK$10,090.

They ordered pricey dishes, including 21 bowls of eel rice, costing HK$78 each, as well as some sushi and sashimi, desserts and alcoholic drinks.

The excessive orders also made some dishes sold out on the online ordering system.

A spokesman from Genki Sushi said the restaurant ended up charging the man only based on how much he ate in the restaurant, not the items ordered by the netizens.

The man later deleted the original Facebook post, quit the Facebook group, and even had his Facebook account deleted.

Some netizens commented that the bill was even more expensive than an “omakase” - the Japanese tradition of letting a chef choose one’s order.
