How will you do it?

Guys, what will you do if you are instructed to find out who are the customers or to where does a certain wine supplier deliver their supplies? I mean is there any footprints for it? Im just confuse and maybe a little annoy since chrome is not working properly for me at the moment. Any help will be appreciated.

Do you mean finding it on the Internet, or trying to find it in real life?
Finding things in the Internet tend to be squeaky clean.

In the internet. care to tell me how GK? I tried looking at supplier website, hoping to look for testimonials and stuff that could point me on people or company names, but the website has no testimonial page.
