Should a waitress, without teeth, be allowed to serve food?

This is a delicate situation with me. I have known this person for many years. This lady has been a waitress most of her life. She served food, to the public, in a well-known restaurant. In her younger life, she had mouth cancer and lost all her teeth. Dentures are not possible. She was terminated from her job, because of a customer complaint of her having no teeth. This is a nice lady and is now unemployed. The reason for her termination is not clear, but she states it was not because of lack of teeth. Question: Need your opinion…....would you object to having your food served to you, by a person that had no teeth?
