He makes 185k, works long hours and doesn’t have kids. If he wants to treat himself to an expensive coat and go to half a dozen gigs a year - or a dozen, I dunno - who cares? If he goes to these things, he can get into the VIP lounge. It’s probably nicer in there and he gets less grief from random drunks on his night off.
The fake social media accounts is separate. It’s not a great instinct, it must be said. Funny that he actually had his own fake Facebook account - calling himself Eric Howell - so he could use it to stay in touch with his friends/family. (He handles that non-scandal better than his tetchy response to the non-scandal about him living it up at Kylie)
Anyway, the authors of that biography ran the book by Varadkar so it’s weird that he didn’t suggest rephrasing the line about fake social media accounts. Maybe, as others suggested, he was happy enough with the inevitable headlines that would follow?
