If I’m not too lazy (heh ?) I usually go to a minimarket/convenience store nearby my place to buy lunch — onigiri (?), sandwiches, omurice (fried rice with ketchup, topped with omelette), or all of the above.
Whenever I’m there, the place usually packed with folks from nearby office buildings — and they are there to buy lunch too or snacks or some stationeries.
I guess I have this soft spot about convenience store. I love how they provide conveniences, some kind of a la carte needs for folks in a hurry, or a place for tourists to stop by and buy some necessities (during my trip to HK, my very first question was, “where’s the nearest convenience store?” ?)
