I did see a scammer on the bus this morning though. She got on the bus, claiming she couldn't find her money in her purse and and had no bus pass. After about 30 seconds of time wasting, the driver told her to sit down - but pay him before she got off the bus.
She was well dressed - designer sunglasses, designer handbag and plenty of jewellry, and she made a big act of searching through her purse. I was sitting across the aisle and reading a magazine at the time, but she made such a production of it, I couldn't help but glance across at the end of every paragraph.
Around paragraph 20, I noticed that she in fact had a $20 note in her purse - but as soon as she found it, she buried it under a stack of receipts (she had about 50 taxi receipts I noticed - her purse had more crap in it than most septic tanks). At paragraph 40, she made a huffing noise to say, "I can't find it", and then gave up the search. She then pulled out a new looking phone, and checked for messages. Finding no messages, she then pulled a new looking Blackberry and spent the rest of the trip into town with her nose in the Blackberry, doing her best to avoid making eye contact with the driver. They looked new to me, because my phone (a bit over a year old) is scratched, battered, cracked and worn down to bare metal in most places.
I hoped she would get off before me, so I could yell, "Don't forget to pay the driver with that twenty before you get off the bus", but alas, I disembarked before her.
