it would have done
if only he hadn't left his phone, the one he bought just for this occasion, in his van.
also as he said he would put the chip in an old phone- why would his missus worry about this???
so the conversation WOULD have gone
'i see you are using your old phone'
'yes i am expecting a call'
'ok'
except in his house it goes
'you are using an old phone'
'i am sorry'
'thats it we are finished'
which sounds more likely??
