Yes, I pack my dinner for lunch the next day. No, not because I'm stingy and wana "harn". Eh, you everyday eat out also will be sien, kan?
I pack my own lunch from home, say, 1-2 times a week. Sometimes more. Depends. Like for the past few weeks, due to the bad haze (and water ration issues), the guys in the office were reluctant to eat out for lunch, so we brought food from home often. If I decide to skip dinner that day, I would pack my dinner to work for lunch the next day.
I'm only a glutton on weekends, but am absolutely a normal human being on weekdays. I only have a cup of beverage for breakfast, a bowl of noodles (or whatever the others are having) for lunch when I'm out with my colleagues, and skip dinner sometimes. Oohhh sometimes my mum and the mil give us food & soup to bring home too, usually on Sundays when we visit them. The food can last for two days, sometimes three - max.
Just to share what's in my lunch box if I pack food from home. Pssstt, if you see canggih dishes, means they are from either my mum or the mil. If you see "chin tan" or "chau choy" or baked beans, means they are from myself, tee hee.
