get go

I was third person in the line with my cart and im pregnant .I decided not to go to priority lane since its not picked time, and its few more step. I did forget some snack so i leave my cart and took 5 steps to grab some choco mucho for my kids., when i returned almost finish the last customer so im next , i felt so bad when the cashier grab the closed signaged and put on the table without a word. And the cashier was with the senior cashier and told me to go to priority lane. They dont gave me a chance since im the last customer. super rude and no proper mannered worker they, i never go there anymore. and i went to another counter after go to customer service for a complaint and i hope they will some action.
