We don't often get to see Floyd Mayweather just really being himself, even on shows like All Access, where a lot of things are just too convenient to be totally real, if you know what I'm saying. (It's reality TV, is what I'm saying. For better or worse.)
But here's a clip that isn't significant or meaningful or anything like that, it's just Floyd breaking someone's balls over putting honey in his coffee, which admittedly is an odd thing to do. Mayweather isn't really yelling at the guy (Marcus, apparently) or being a jerk, he's just busting chops over a minor little screw-up, then tells another amusing story about the guy.
I don't know, I find it interesting sometimes to see guys when their guard is really down more than normal, and I think this brief clip captures that. You're perfectly free to not give a shit, but just know this if you ever end up on #TheMoneyTeam: don't put honey in Floyd's coffee.
In fact, probably don't put honey in anyone's coffee, ever.
