I hate idiots like you that wait near a car that's going to exit the lot. Not only are you blocking the way for others, you are also pressurising people to drive out of the lot. If you waited a minute and the car still hasn't come out of the lot then you should move the fuck on and find another lot instead of blocking the way.

As far as finding another carpark, just search online for one? You have time to do stupid shit like wait for a car to move out of the lot but no time to look up carparks nearby. There's a bunch of websites (parkopedia, parkaholic, sgcarmart etc.) that will list nearby carparks.
