After finishing apprenticeship my boss wanted to print every source code of our website (also CMS) as well our onlineshop (the whole not just own modules).
His intention was to inspect the code offline so he can i.e. lay sheets side by side for an better overview about any relations. Ich knew that he won't believe me if i tell him that's a bad idea so i printed over 10000 sites of source code.
He never looked a single time over it
