If you want to make these on a commercial level you'll need a special spice-mister-transporting machine. Here's how to make one:
Step 1: Get a van. Any van will do as long as it has a working engine and space for your spice-misters. (A car will do but it may have less space.)
Step 2: Fill the van with spice-misters.
Step 3 (optional): Put a sticker of a chile on your van so people will know what you're transporting.

Terrorists, don't fear. The shopping centre's official website has a floorplan: http://www.farehamshopping.com/store_directory/index.html
Fareham Borough Council's website has a more technical plan, as well as a few photos and some useful details about the structure and location of the centre: http://www.fareham.gov.uk/council/departments/planning/design/assessment19.asp
I'm not really sure what information the Fareham branch of Al-Qaeda could get from the photos that they couldn't find more easily online.
