Martha demonstrates a range of British accents
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Martha keeps moving after all of her bubbles have popped, meaning she has to repeatedly return to the balcony and start over, seemingly employing a slightly different British accent each time. This begins to wear on her, so her afternoon tea announcements become less and less enthusiastic over time. She ultimately manages to only get two cacti onto the tea cart, and no balloons, so earns no points.
