PC World do not employ people, they have a special facility where they are grown or cloned or both!
Walking in to PC world on the rare occasions I do venture in to have a bloody good laugh at the prices, well they make me chuckle, £199 for a UMPC notebook that I can pick up for £129 with better spec... Well it makes me laugh.
I would say that if you were in MacD's flipping burgers, your prospects of moving up the food chain are better than working for a retailer like PC World.
