This has to be one of the stupidest things you could possibly do ! So your phone gets lost or stolen ..... Now you have no means to communicate, and no means of buying any,no means of paying for a bus or train or cab,so I hope you have your car and keys,although you can’t get out of the car park or pay for fuel.
And it is after midnight and it’s raining......
There is a very descriptive phrase for this but it has a vulgar word in it !
