Called him x2 on his mobile this evening and it rang out, so I gave up. He called me back about half an hour later, saying he's just been stuck in a tunnel for 20 mins between two tube stations.
So why did it ring if you were underground - I say. Hmm, weird - he replies.
I feel sus so I call TFL - no reported delays and the chap said he would def know about a 20 min delay as it would have a massive knock on effect on the whole line.
AIBU to think he is bullshitting me. He will NEVER admit to this. Arrrgggg.
