The thing is, the workers are human. Human needs food. Apparently we all do have about the same period of lunch time.
That building have a cafe on the third level. So everyday on 1 pm the place would be crowded with people. The rule is plain and simple : first come, first serve.
Sometime you havr to wait 20 mins just to get your order of plain fried rice. That's mean you just escape your burden of work and get into the burden of waiting and waste quarter of your precious lunch time.
What I do is exactly the same. I would go to ground level. There's a small side cafe name "Harveys". I would have my white coffee and cold nasi lemak. Sometime I would have tuna sandwich. Got 3 tables with 3 chairs each, and my place is always at the second table as the first one will always occupied with this Indian uncle drinking coffee and reading News Straits Times.
The point is, I don't mind eating cold nasi lemak every noon with my mind thinking of other hot delicious meals I could get on level 3.
Well, my rule is simple too : I won't fight, I won't wait, I won't argue, I won't talk for something that aren't worth my time.
