How do you deal with different customer behaviours and personalities to achieve customer satisfaction?

Just respond as non-lethally as possible.

For outgoing or chatty customers, just imitate their behavior, really. Be friendly to them and if they feel like striking up a conversation, just go along with it.

For shy or awkward customers, be as non-threatening as you can so they don't feel pressure into certain things.

For angry or mean-spirited customers, just reflect back their vents in empathic tones. Do not be patronizing or hostile back to them at all or depending on how perseverant they are, they might just file a customer complaint against you. And that does look bad.

Unfortunately the field of customers is dotted with the boring, the rude and the overly-friendly. Just put your natural reactions aside and remember what you're trying to accomplish: them buying things happily.
