************** against single parents

This morning I went to checkers selcourt springs to buy groceries as I got to the front of the line I was told they only allow one member per family into the store, I am a single parent with a 3 year old. I can't leave with anyone so she needs to come with me. I was treated so badly, please tell me Checkers management what do single parents do with their children when they want to shop at your stores?
