"Made me feel like I shouldn’t be there"

Upon arrival for my appointment, I was greeted by a young, pleasant receptionist. I had arrived a little early. The receptionist asked another member of staff about my appointment and they very abruptly answered that my appointment wasn't until 10:40am, go away and come back in 10 minutes. I felt very uncomfortable with this staff member's tone, which made me feel like I shouldn’t be there . I’ve since been in and had the assessment which was very efficient and an extremely excellent service which is provided .
