mucus

i think someone should really rethink nose blowing etiquette. i firmly support the no-nose-blowing-when-dining rule. it's repulsive to expel mucus out of your nasal passages over lobster bisque. why then is not considered distasteful to do so in the work place?
my mucus-laden colleague is a lovely guy. in all other respects he's consummately thoughtful and respectful. the consistent nose blowing though has to stop. if it were a demure activity, that would be one thing. if he seemed shamed by the process, i would be more able to forgive. but this incessant activity is shameless. it's an impassioned, full force effort. i don't even think it's crossed his mind that this borders on noise polution. the preliminary blow followed by a forceful nasal sound is really becoming too much for me to bear.
this must somehow be an hr violation like my other colleague who has a weekly nail trim at his desk. yesterday he asked his desk mate to lend him her scissors; he then proceeded to trim his nails on their shared space before scooping them into his trash bin. she had to excuse herself so she wouldn't gag.
