Rude worker

So I am 7months pregnant and wanted to shop at Jet, when i walked in the sanitize machine doesnt pour enough sanitize to sanitize your hands so you have to step on it a few times. So my daughter of 4years old step on it 4times cause im a paranoid mother so all my children know they have to sanitize, the worker at Jet in Greenacres Mall PE started to scream on my little girl, when i confronted him and ask to see the manager he said i must go to the till which was very full as month end. I ask him to please call the manager i cant stand in the row for hours as i am pregnant he started to laugh at me. He also doesnt wanted to give me his name. How rude of Jet's workers. They will never see me again.
