14 The Gift Shop.
They arrive in the gift shop. There are many 'Cookerama Intergalactic' bun models like the cupcake model over the entry gate, teaspoons sporting the cupcake emblem; mugs with the cupcake emblem, too; even magnetic emblems to stick to the walls in your spacecraft.
Workman 3 whispers to a girl by the till and she goes through a door behind the till and returns a moment later with a big thick photograph album. She puts the album down on the counter and opens it, she leafs through it briefly, then points to a photograph for the Doctor to see.
"Cybermen?" the Doctor questions. "Why would they be here?"
The Doctor notices the date of their visit.
"They weren't any good at cooking!" Workman 3 jokes. "The pans kept flying off the stove and sticking to them! They did get very frustrated."
"Well, thank you," the Doctor says. "I'm not sure quite what to make of it. Was there anything else odd happened while they were here?"
"Not really," Workman 3 says nonchalantly. "No-one else liked being in the baking room while they were in it. The room gradually emptied during the day. Some said they seemed to be offering 'upgrades' whatever they were. Oh, and there were a lot of unclaimed spaceships at the end of that day."
There wasn't much for the Doctor to go on. A Cybermen's day out? Do they do that?
"Did they say where they were from?" asks the Doctor.
"No," the Till Girl says, "and actually, they didn't pay for their session either. Which brings me to another point. How will you be paying?"
"I always pay cash. Is that alright?" the Doctor asks.
