Reaction was swift, with mothers flooding to the official Petsense page to complain about Ms Clark and threatening to stage a "nurse-in" at her store.

Ms Clark clearly wasn't pleased with the idea, and messaged one of the mothers who complained - Kim Reindeau - to complain about her character.

"Do what you want, but I find it very immature to know that you as a mother would go out of your way to come to a place that you know I work at and breastfeed," she said.

"[I don't care] who breastfeeds when my kids aren't around, pulling your boob out in front of my kids on purpose just to prove a point is simple represented by who you are as a person."

Petsense confirmed on Facebook Ms Clark had been fired, and said her views did not represent those of the company.

"We absolutely would never condone violence such as was recently posted by a former Petsense employee," a spokesperson said.

"These are her individual views and do not reflect the views of Petsense or its employees. This individual is no longer employed by Petsense. We sincerely apologise to all of those who have been affected by this situation."
