Hi,
I work part time at my LQS. We always greet and ask customers if we can help them find something or help them with anything. We don't hover, nothing bugs me more than going into a shop and have the worker hover next to me continually. We ask, get a reply, and then either help or tell them to ask if they should need anything....and we check back with them in a bit.
The owner of the shop I work at is fantastic with names...she remembers first names of people who come in just once a year when they come to town to visit Grandma! Amazing! It really impresses the customer, too
