You know you're from Perth when...

 (Don't even think about it, pal)

(pic stolen from this guy)

You get onto the bus.

You look for a seat.

All of the double seats are taken, by one person each.

Each of those people has politely sat on the window side of the double seat.

(Probably reluctantly, mind, but people are looking.)

You kinda roll your eyes internally and decide to stand.

Too many cunts on the bus.
