Why doctors in India write prescriptions with bad handwriting? Is it intentional?

See, someone might have got habitual bad handwriting skill. He may be a doctor also. That's natural. But where many doctors do not have got bad hand writing, and in fact their hand writing skill is actually good enough, still we find that in most of the cases they write prescriptions very badly, so that you cannot understand what is the name of the medicine written there on that prescription. Sometimes even the compounder/chemist or the medicine salesmen fail to understand it, and sometimes they give wrong medicines to the patients which are almost similar in spelling to the drug prescribed. Is this trend intentional? So that the next time that patients are attacked with the same disease, they cannot follow the old prescription which really worked for them and once again they have to go to that particular doctor with the same prescription and the directions written therein in exchange of another hefty visit-fee? Do you think that all the prescriptions should be neatly typewritten or printed with a computer, so that everyone understands it that what is written there in the prescription?
