My 15 Minutes Agony With A Lady With SmellyHair In A Queue

I was in the bank some few days ago for some
transactions and hell the queue was long and thick,
it happened that i was standing behind this lady
with a particular kind of braids named after this
popular reggea star...and ol' boy the kind of stench
oozing out from there was just unbearable, i turned
my head left..no,turned right..no way, not even the
serene and chilled atmostphere could help me.

When it became unbearable i was forced to bring
out my handkerchief and stylishly cover my nose. I
heard some suppresed laughter from a guy who
took notice and the lady became embarrased. it
was not my intention to embarrass her as i have to
save my life.

I know most ladies dont wash their hair, but what
stops them from using treatments like hair mousse
or sheen and whatever needed to be applied to
keep the foul odour out is what i dnt know.

Or if the hair got wet by mistake and the odour will
be noticeable, what prevents such people from
using caps or scarfs to cover their hair?
Any advice for such type of ladies here will be
much educational healthwise, as this is a serious
breach of public health.
