Sing Songy waitperson.

Is she a waitperson or a childcare provider.
Where do they all come from? There must be a school where one learns the language of sing-songy patronizing table waiting. There must be at least one per each restaurant.
Pardon me if it seem a bit sexist but, what I’m trying to describe happens mostly with teen girls and young women. And it might happen with young men waiters as well. Really don’t know.
But anyway, who teaches girls and young women waiting tables to sound like someone teaching a toddler to enjoy eating all its food.
There is a practiced high pitched nasal tone they perform. Sounding something like a young Edith Bunker with way too much smile in their voice. Almost like they might break out in song and dance. Hi there, my name is Breanna and I will be your humble server tonight sweetie. Oh, my oh my can I really really take your drink orders?

All of this just for the price of a generous tip. But don’t get me started on the subject of tipping.
