MILF Stew

The ad copy reads:

“Think of her as your mother.
She only wants what’s best for you.
A cool drink. A good dinner. A soft pillow and a warm blanket.

Training in service, not just a beauty course.
Service, after all, is what makes professional travellers prefer American.
And makes new travellers want to keep flying with us.
Se we see that every passenger gets the same professional treatment.
That’s the American Way.”
