Question About Overbilling Conversation I Overheard

I was waiting for a hearing in the hallway of the courthouse when I overheard two attorneys chatting. One was saying how they love taking cases in a particular county because it’s far from his office but close to his home so he could get to the courthouse in 15 minutes but bill for two hours. As someone who has worked on contingency for most of my career, I would assume that what he is describing is classic overbilling and an ethics violation, but these guys were chatting so openly that I’m wondering am I wrong or were these guys just clueless to be so vocal about their ethical violations.

What’s the verdict?
