No. Not quite so. First of all, he did say please, twice. Second, he is a absent-minded professor – hence his impatientness. Then also, bear in mind, he had so many responsibilities, he had no time for niceties. Did you head a surgeon request “Kind dear assistant, could you please graciously kindly hand me over the scalpel”? (Even if you did, it’s not the way I perform operations) And he had the whole machine (kugelator, grepslink etc.) to take care of.
Teachers are faced with this sort of dilemma on a daily basis. To afford one more attention on the expense of the whole class, school. It’s actually better middos to take care of a kllal than a yachid. – In my humble opinion –
