"dental receptionist chewing gum really rude"

The dental receptionist is never at their desk and always has to be called in by other staff members. When they come back they chew their gum very annoyingly opening their mouth even when they speak to patients in their rude manner. I have been there a good 5 times now and this happened every time I got there. Not very good service at front desk. The dental treatment is very good however very happy with the dentists and dental nurses made my child feel very comfortable. thank you
