Taxi drivers

I usually enjoy conversing with taxi drivers on my rides home, but today was an exception and i so very have to bitch about it. Anyways, here i was, taking a cab home at 4:30am, utterly spent from a long dull day. Yearning for some sleep, i was like an explosion awaiting ignition. And that was exactly what that damned cabbie gave me.
After paying $16.50 for my $16.45 fare, i stared at the driver, awaiting some form of acknowledgement. Instead, the driver's face crumbled into an awkward mess, effectively giving me the look. (the is pronounced with an italian accent.)

Cabbie: Your fare is $16.45.
(the look.)
Me: Hmm..

At first, i thought, hey maybe i underpaid him or something, but i double checked and i did indeed pay him $16.50. So what was the problem here?

Cabbie: You want me to change you 5 cents ah?
(the look intensified.)
Me: Huh, oh, err.. it's ok, you can keep the change.

Come to think of it now, i should have insisted on the change and threw it back at him darn face. It's 4:30 in the morning lor, the last thing i needed was someone to piss me off.

To that darned cabbie: I hope you are happy, now that you are 5 cents richer, loser.
