Probably isn't the best way to handle that.  Doesn't have to be the best, just good. And it's not just good, but fucking fantastic. Fat shaming absolutely must become more common.  Just do what I do and take a really long time at the vending machine, and get trail mix to make them feel guilty. Then throw away the trail mix because it's loaded with sugar and go back to drinking black coffee.  That's way too passive-aggressive to do any good in the big picture. It will piss off the individual fatty, but all it will do is make them eat more (which is good, send them to Lord Beetus as fast as possible), but only affects one fatty at a time. But openly fat shaming lets all the other shitlords see that it's ok to do so. It's multiplicative instead of merely additive. It also sends the triggered fatties (a whole group of them, not just the one at the vending machine) to Lord Beetus faster.
