The more time you spend looking for your lens cap and various other photography accessories, the less time you have to focus on your client and get the shot. Even if you are a hobbyist photographer, the perfect photography opportunity seldom waits so if you are fumbling for something in your camera bag you may end up out of luck.
Photography Tip: Keep your lens cap in your right front pocket
