A breakfast food stall in Taoyuan City's Zhongli District, Taiwan has gone viral for upholding a banner that serves as a "warning" to their customers. Needless to say, the message is now clearly received. 

The banner, which includes a clear photo of the owner, states, "Those who are 18 years old and older are not to refer to the lady owner as "Auntie" in order to ensure the quality of the food served."

One unsuspecting customer, however, made the grave mistake of calling the lady boss "auntie", to which his breakfast request was met with no response. That was until another customer, who happened to be seating next time, pointed out the banner. Learning his lesson, the customer rephrased: "Beautiful lady boss, I would like a thick slice of smoked chicken with onion and a glass of cold milk."

The moral of the story is: Remove the word "auntie" from your vocabulary if you wish to be served good service the next time you go outside, or prepare the bare the consequences.
