Pay Phone?
Did nobody else notice that the phone part was so insignificant to the revenue stream that phone calls are free?
If the supposed main purpose of this is a payphone then why don't you have to pay for the phone calls?
Pay. Phone. Perhaps the clue is in the name?
Can it even be classed as a payphone if you don't have to pay?
Then again I almost never make or receive phone calls on my "mobile phone".
