One of the best things about Waitrose is their staff. I don't what they do behind the scenes, but they have by far the best trained staff of any supermarket I've been to.
Without exception, all the staff on the floor are smartly dressed, know about produce and are friendly. My guess is that they pay better, and there's that thing about staff in the John Lewis Group all being 'partners' in the company, so if the company does well, it reflects directly in their salary.
