Saying, "How are you" is a big one that typically gets a one word response so it isn't over whelming for you to understand :)
Make two thumbs up and put them together.and twist the right one down. Thats HOW. and then point to the customer. How-Are-You. But make sure your eye brows are up to show that you are asking a question so its clear what you are doing.
Same thing with asking "Are you having a good day?" You can sign "Good Day" while raising your eyebrows.
