I don't know the specifics (but I'll try and find out next time I'm in work) but I know that in the IKEA I work in we've had similar things (smoke bombs in the air conditioning ducts, fire alarms set off) as distractions so people can try and get into the cash office.
I don't know about other countries, but I know IKEA UK has been suffering with the economic downturn as much as other retailers. It's definitely quieter than it was a couple of years ago (we've gone from a midnight midweek close to 10pm one over the last 2 years, primarily because it's no longer viable to stay open) It's not struggling, but it's feeling the pinch (I'm looking at redundancy because of the change in hours )
Here in Shanghai it is HEAVING. They love it. A new one is just about to open this month, so we will have one on both sides of the city. Lots of the locals go there for the cool air con, to escape the heat and there are always people fast asleep on the beds and babies asleep in the cots! They are certainly not struggling here, in fact quite the opposite. Didn't know about the alarm clocks, though.
Ooohhhh, Ikea Meatballs...... I hear Ikea did sign a lease for land in Auckland a few years back, but they couldn't get resource consent .... some daft twonk refused it on the basis that the traffic system wouldn't be able to cope. Clearly someone who has never tasted Ikea meatballs.
