Worked there festive season 2012
There were two things that got me annoyed.
1) In a warehouse exceeding 150m by 200m there is one toilet in an area that you have to walk the long way around to get to.
2) They mumble about having some leeway about the time walking to your breaks, including queueing to get through security, but then they remind you to be back within 20 minutes of going on lunch. Seriously, I never bothered taking my shorter breaks because there was no time to get there and back.
