A screenshot of a message sent by an Foodpanda rider to a female customer has gone viral after it was posted on Facebook, drawing heavy criticism from netizens.

In the chat, the driver sent a message to a customer, saying "Customer when you come out to pick up your stuff, please wear a bra. I don't feel comfortable [if you don't wear one]."

Apparently, the rider was referring to an awkward incident in which the customer he was supposed to deliver food to picked up her order without wearing a bra.

The post, which has been shared extensively since it was first posted, drew criticism from netizens, especially women who believed the message had sexual undertones.

"Whether a woman chooses to wear a bra or not, that is her personal right. It doesn't mean anyone can harass or humiliate her," a netizen wrote.

Others defended the woman, saying many women choose not to wear a bra at home in order to feel more comfortable, and she probably did not think it was necessary to put one on for a couple of minutes just to pick up a food order.

However, some disagreed with their view. Several food delivery riders shared their experiences, but others said they believed these women deliberately wore no undergarment to seduce them.

Foodpanda Thailand later issued a public apology, pledging to investigate the matter and punish the rider in question.
