<em>Is this real situation?</em> If it is .. you might want to give her a jacket or a light sweater to a least cover the stain. Or, you can go to the bathroom and try to wash it off. You can also probably ask an employee there and they might help you with it (though i wouldn't think they would help but just a recommendation)
hope this helps your friend if this is real ❤ from peachimin
