Hungwee..... 
Anyway, tomorrow morning I have to attend yet another
totally-useless lab safety certification course.....
I say 'totally useless' because I had actually attended it two
years ago..... at that time, certificates of attendance were not
issued and the only proof of attendance was a single piece of
attendance sheet kept by the campus safety office....
Then for this year's lab safety audit, all lab users must
produce the cert (which my batch didn't have). Then when my lab
techs tried to contact the campus safety office for the attendance
list.... it was missing! 
So, because of the utter incompetence of some idiots who
couldn't be bothered to keep proper records, me and some other
postgrads have to re-attend this course!
