Great Expressions Dental Centers review: front desk

The front desk lady Brittany should not work with customers and she definitely shouldn't be the first person you see when you walk in. She has a disgusting attitude and she constantly talks trash about customers as she is sitting behind the counter. She's rude and nasty! She acts like she hates her job. I'm currently sitting in the office and she is calling patients to give reminders for their appointments, a patient called to say that they didn't get a reminder, she proceeds to change the contact information and as soon as she hung up, she turns to her coworker and said "I hate her, it's not my fault she didn't change the number, I hope she misses her appointment. I'm not in the mood today for these people"... I've been to this location and she is NEVER in the mood for people so why does she work with people
