I've noticed that especially for younger and lower income Asians the apartments/rooms don't come with what we would call a kitchen or kitchenette. Instead there will be a cabinet top adorned with a hot water pot, a rice cooker, and maybe a microwave or hot plate. So instant coffee (usually Nescafe) or 3-in-1 coffee (instant coffee, creamer and sugar all mixed together in packets) tends to be the norm. In Thailand there are still coffee carts where you can buy hot or cold Thai coffee, but it seems to be more popular with older rather than younger Thai. Thailand also has lots of coffee shops these days, including overpriced Starbucks, of course.

I often bring back a couple of 10-packs of Khao Shong mint coffee mix, but I only use a couple of spoonfuls added to brewed coffee as a full cup of the stuff is too sweet for me.
