Answer:
Be polite.
Explanation:
As the saying goes, kill them with kindness. If someone is being impolite, either 1, look at the situation i their shoes. Or 2, just simply keep on your professional face, don't lash out, don't act with hidden violence (Etc; slamming money on the counter for them to grab) Just simply apologize and continue working. You're only there for money, or to just have fun, or any reason at all. There's no need to have one person ruin you're mood.
You should begin panning a second or two after you press the shutter release button on most cameras. This statement is true. It is necessary that you perform this action so that you will be able to capture the image well and not blurry.
