Subway

On January 15, 2021 I visited Subway between 7:30-7:45 PM in Mebane, NC (1244 S 5th St)
When I asked a question the lady laughed at me and whispered in the ears of her co-worker.
All the time both stared at me as if they were serving food for free or as if I was from an other planet. Tried to reach out to the manager, called several times but either no one receives the call or says the manager is not available.
I myself have worked for customer service and I know how customers should be treated, at the same time expect others to treat me well or at least as a human. I wish these employees are trained again accordingly.
