A Brisbane coffee shop owner would be happy if a female customer who changed her baby's nappy - twice - at a table while people were eating never returned.

Meanwhile, the mother of the baby has written a scathing review on Google about Park Bench Espresso Bar in Bulimba for the reception she received for changing her baby in front of dining customers.

The review, attributed to Stephanie Plahn, first praises the quality of the coffee before taking aim at owner Jocelyn Ridgway and other customers.

She says her baby is 12 weeks old and that she put a mat down before changing the nappy.
