There's the 50% more surcharge.
And countless teens, like myself, who hang around town or else
where till missed the last bus to get home.
Also the clubbers and pubbers.
Some of the taxi can be cater to staff from various place too.
Like when I use to work in Airport Terminal 3, the shops closes at
1. So have to take taxu back. Morning shift starts at 6, so have to
take taxi go.
