As a licensed engineer & pilot, I see no issues with this. Why would you take any paperwork on to the cold (probably dirty) hangar floor?
Their working practices appear no better or worse than you'd see in the UK or any EASA standard hangar, and I'd argue this point with anyone.
I think the OP intended this to showcase the capabilities of their company perhaps, and we've managed to swing it round to be a Robbo & Robbo Engineer bash thread.
