A little politesse goes a long way.
Some handy tips:
It’s cheaper to stand at the bar, order your coffee and croissant and eat it standing. DO NOT take it to a table and sit down.
Bread comes with most meals. Don’t ask for butter, it will be considered a tartine, a breakfast item.
Food can be rich and filling. Don’t ask for a doggie bag. It’s okay to leave food on your plate.
Parisians have excellent manners. Always say “bonjour madame, monsieur, mademoiselle” and “au revoir madame………” when coming in contact with your fellow man. And say it softly as best you can, no need to shout.
