complaining does pay

i whine and gripe and bitch about a lot of stuff, but mainly to whoever is around. i seldom make it official. i'm normally too passive to do anything more than whine, gripe or bitch.
anyway, certain conditions made it necessary for me to take action. what conditions would that be? i'm most irritated and frustrated about bus services.
true, singapore has the most reliable bus system, the public busses that is. the private bus companies, well that's another story.
now that i'm working in a location that requires a shuttle bus to take me in and out of work premises, i expect the bus to meet the time schedule on the dot. there is this one driver who got on my nerves lately. he'll only arrive at the front gate at the time he's supposed to go out of it. if it happened only once or twice i wouldn't mind. afterall, he's only human. nobody's pefect. but he's been doing it for a few weeks.
what do i do? i wrote in the the logistics officer and explained the situation. following day, bus came and left on time, and i'm all smiles.
the end.
