This is a great one. Set just after the checkouts in this Swedish furniture store. To the right is a hot dog stall. Anyone who knows Ikea will surely buy an Ikea hot as their great value at 49p. So you'll have loads of customers standing around. You've also got a taxi stall that you can see to the left. This private payphone rings nice and loud and it'll get the attention of everyone around.
