Heh, I prefer having lunch alone as well. No fuss over waiting
for everyone to gather. No fuss over non smoking colleagues. No
fuss over location. No fuss over seats. Plus I get to catch up with
the news. 
But yeah people start to think I'm anti social etc. But I wind
up getting more work done when the whole office evacuates for 1 or
2 hours. Lunch takes only 15 minutes. Plus 5 minutes for smokes. I
save 1.5hours. Surf sgforums, 2 hours. So I lose only 0.5hrs.
lol.. o.k. there is some truth functional logic in that.
