Door-thumping

Let me introduce you to the art of door-thumping.
Ever ran 26km/hr over 200m to catch the bus, only to have it pull out of the stop while you stare helplessly at your ride when you'd only been a mere distance of 10 inches (your nose to the door) from it, because the driver was looking the other way for oncoming traffic as he got ready to pull out of the stop so he didn't see you?
Yes, that has happened to me too.
You may try waving vigorously and shouting (as I did), but chances are you'll miss your ride because the driver won't see or hear you.
Therefore!
I discovered the art of door-thumping.
It's simple business. Any idiot can do it. Just raise your hand and pound on the door. The door won't break, your hand won't hurt (if you have sense enough to use your palm instead of your knuckles) and the bus driver will definitely notice you.
Eventually (when he has overcome his shock) he'll press the 'door open' button and Voila! You board the bus :)
Simple and fuss-free, ain'it, and you don't have to grumble for the next 15mins waiting for the next bus to come.
I've tried it! Success rates have been 100% so far!
The next time you're staring at closed bus doors, you know what to do :)
