Special occasions lead to special food at times (e.g. Hari Raya,
Deepavali, Christmas, etc).
Also, we were served good food once in a while for no clear
reason at all.
And when I was at SMTI, I remember that the breakfast sometimes
consisted of..... salmon patties.
Quite a few of my friends hated them, but I liked salmon
patties. And they're as expensive as heck - I kinda remember seeing
that they cost $3.50 for two at NTUC.
I'm one of those who hated them. I was a trainee at SI and you'd
get salmon patties like 2 - 4 times a week then 
I thought they tasted really strong and artificial, even told
mookie that chewing on them is like trying to brush with salmon
flavor toothpaste
