If the "half a job/wrong way" works just as well (for me at least) as the "proper" way, could you please tell me what advantage the proper format has? I really want to know...I'm not trying to be 'funny'.
Not directly related, however, here goes.
You take your car to a mechanic for a service, he changes the engine oil, but fails to change the filter (containing about a litre of the old shitty oil) he then refills it with new oil.
Result: HALF A JOB.
To the driver of the car, no real difference in performance or anything else.
This would also be true for many other things in life, doing half jobs work fine for a lot of people, however they do pay for it in some form or another in the long term.
