If you want to take really quick & sneaky photographs on the street without putting your eye to the viewfinder, here’s a sneaky trick.
Setting your lens in manual focus mode, and setting it at its Hyperfocal distance will allow you to take photographs with a great deal of flexibility, often allowing you to shoot from your hip, or while supporting the camera on a steady surface. Very un-obtrusive.
Remember that Hyperfocal distance works best when you’re using a rather small f-stop, like f/16 or f/22, so set your camera in aperture priority mode and shoot on a relatively sunny day, and you’ll find nearly everything in focus. Of course, this works best if you’re using a wide-angle or normal lens.
I’ve managed to get everything from infinity to objects around 4 feet away in good focus while trying this technique recently, with my Nikon F3 and a 50mm lens. It worked great!
