Sonic Drive-In review: Employee

I called the sonic drive in on Athens highway in Loganville, Ga to address a bad experience with an order and spoke with a woman who gave the name "Sarah". Before the phone call was ended, I could clearly hear her say "GOD, she was a [censored]" to (I assume) another employee. Now I understand people have freedom of speech and can say what they want, but this was offensive and unprofessional. This experience left me questioning whether or not I really give this impression to other people i interact with and It's (to say the least) damaging. Upsetting as it was, this individual is fortunate that the lord walks with me and does not permit me to respond to negative people or insults directly. Otherwise, I would walk right in there and bless her with the feeling of regret. I hope she sees my complaint and knows that I heard her words because "GOD" didn't. He was here next to me. I would ask the lord to bless her but I sincerely doubt that she would appreciate it.
