Is it possible he was emptying his colostomy bag?Djokovic took an MTO, was taking long time between serves and was cheering and fistpumping on UEs. If they same was done by Rafa, you would have a 100 posts here in 10 mins!!!
I can't comment on the MTO though, there is no way that I, sitting in my room, know about the conditions and his health issues. It is fair not to comment.
