From the article, it's basically as they say the comfort break being taken out.
Yeah, I've since seen that elsewhere. It's up to the umpires to police it, I was under the impression absence from the field had to be approved by the opposition captain anyhoo. I don't see any great problem with them changing their boots or shirts since batsmen can change their gloves, bats etc. Taking showers and feet up is a bit much though, maybe they should have an official with them to monitor their activities.
