Family Dollar

I was in one of your stores today #09247 purchasing some items, when I suddenly needed to use the restroom immediately if not sooner (i'm sure we've all had this happen) I was informed there were no public restrooms which I couldn't understand because I was a paying customer. My question where do employees use the restroom? Why aren't they available to customers? Long story short I didn't make it to restroom facilities in time. Do you know how embarrassing this is and totally uncalled for. Please explain.
