Now, unlike that pig that made a big deal about what he thought was "gluttony", I define "gluttony" as when a person consistently eats so much that it has a detrimental effect on health. Such eating would not be the result of another disorder, such as an endocrine problem (being fed monosodium glutamate as small children does disrupt the metabolism, leading to being fat and very hard to reduce). Being greedy is just one facet.
And just being fat isn't enough--people are fat because of the poisons in our food that the manufacturers put there on purpose, not getting enough exercise, eating too much of the wrong kind of food, not getting enough sleep, and/or stress. You can also get fat by undereating for a few days, then going back to normal eating--repeat, and it will screw up your metabolism. Many pollutants (BPA is one) also mess with your metabolism. Too much fluoride, not enough iodine, and eating too much soy oil or rape seed oil (canola) will also screw up your metabolism. THIS IS NOT GLUTTONY!
Problem is, when a person is like this, they are willing to screw with definitions of words. "Gluttony" can mean anything that gets as much pleasure out of a situation as one possibly can. They do the same thing with other words, and can invent problems to part you from your job and wealth so you can pio-sneer. Very often, they are as picky with your driving (doing 60 on a 55 is less serious than paying attention to the speedometer instead of the road), your music (I see nothing wrong with listening to worldly music--some people think best with no music, but limiting it to Kingdumb Maladies is not acceptable), your demeanor, your grooming (forget to shave or put your tie on a bit sloppy, and you will hear no end), and what material things you might sport.
As for the "stop", that is very common. It's called a "California stop". Yes, you can get a ticket for doing a California stop. However, it is more important to pay attention to the road than to picky aspects of driving. And, while I don't recommend eating 3 Big Macs at a time on a regular basis, no one has the right to, based solely on this, call it "gluttony". There is a big difference between a poor diet and gluttony, and those who are self-righteous are not going to get that.
