A customer has just arrived in the store and is concerned that the store is too big for her to find what she needs. What would you say to this customer?

"May I help you find what you are looking for?"

"Let me find someone that can guide you and find what you want."

Normally you don’t need to ask because if
someone wants something that person will ask. But if not then I will ask her what
she need so I can help her to get that.
