No, well, not in hand but usually its in my purse .... once I was talking to someone on the phone for about 5 mins and then I heard a 'flush' in the background ... very weird and a little gross! I told them I had to go and I'd call them back later,
I didn't.
If its in my pocket it does go in the bathroom with me but ,although I can multitask ,I wouldnt answer it ,I would ring them back afterwards making some other excuse for missing their call.
