i never really liked to lunch with my colliks (my prev job was
also my first full-time job)
cos they always like to flip mountain climb hill to have 2-hr
lunches when there are so many many good choices a 5 min-walk
away... 
Lunching with collicks is beri impt... I organise lunch outing even
with ppl from other depts... mainly for bonding... sometimes talk
issues over lunch is easier...
Besides, once ur network is formed up nicely, when U need
support from other group also much easier... much easier to get
things done...
and besides, when lunching with collicks, u will naturally talk
abt gossips, be it work related or just scandals... this are
information, and we're at an era when knowledge is power...
