A mother changed her baby's diaper on a cafe table twice, then left the cafe a bad review.

An Australian coffee shop owner is shocked after a female customer changed her baby's nappy twice on a cafe table, then wrote the Brisbane cafe a bad review online.

The mother left 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 in the cafe's eating area.

The review, under the name 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.

"I approached her (the manager) upon leaving and asked if she had a problem with my baby and I sitting there. She said in quite a critical tone that she didn't think it was appropriate to change my baby there," the review states.

"To this woman and the 2 other customers who made comments regarding this. Mothers don't need your judgment or criticism. We have enough pressure and stress we deal with on a daily basis. We rarely get the opportunity to get out and have a coffee amidst the long list of things we are doing for our families every single day.

"I am sorry (not sorry) you are so terribly offended by a tiny baby's tiny little dirty nappy that you think it necessary to criticise."

Ridgway told AAP the lady was at the coffee shop for two hours last Friday.

"There were people next to her. We had complaints from a group of older women who did not think it was that great."

Since Ridgway shared the review on Facebook, she's said she's had nothing but support.

"I know in my heart that that was not cool. It's an etiquette thing. She won't be back as a customer, that's fine. I can't afford to have customers like her anyway," she said.

The store's Google reviews have exploded from a handful to almost 40 with almost everyone dumping on Plahn.

"5 stars for not backing down when you were challenged by the lady with the dirty nappy! I would be disgusted if someone changed a nappy while I ate," wrote Alana Templeton.

Another customer wrote "I just wanted to support the owner against the selfish arrogant self entitled post", while Sharna Allen posted "I am so ashamed of my self absorbed generation! show some respect for people around!"
