Can I help you ?   I'm looking for someone who works here , but I lost his business card . His name's Long or Sang or something like that .   Chang ?   Yeah , that sounds right .   There are about twenty people named Chang who work here . What department ?   Let me think ... accounting , finance , something like that .   Eric Chang in accounting ?   That's him !   I'll call him and tell him you're here .   I appreciate your help .   Would you like to have a seat over there ? It'll just be a minute . And can I have your name ?   Here's my card .   OK . I'll have him come up to get you .
