***Don't stand on the furniture*** I must admit that never entered my mind. I know sometimes you have to get in strange positions to get that perfect shot but not a good idea in a restaurant. You don't want to be a distraction to other patrons.
**Don't use a flash** I agree this too is a distraction to the people seated around you. I know there are ways to get around this such as shutter speed and ISO. We will leave that for another time.
**Leave other folks out of your photo** Not always easy to do, but I will make a better attempt:-)
**Other distractions to avoid** Tripods. Don't move furniture to get a good shot. Take your photos and put your camera away so you can enjoy your meal. I am sure there are many more tips on etiquette but overall we should do our best not to be a distraction to our fellow diners.
Get out and try a new restaurant and take some photos using proper photography etiquette.
