At my former job, I inherited a client from a co-worker who was moving away. She warned me that they had some pretty strange requests.
Client: I asked [your former co-worker] to add our web address at the bottom of each page and she wouldn't do it. Would you add it and make it really big?
I explained that I didn't think it was necessary to have your web address listed on your web site.
Client: Well, what if someone is browsing the site and they get a phone call and have to turn off their computer, how will they ever figure out how to find us again?
Me: They can look in the address bar and see your web address there. They could also catalog you in their Favorites.
Client: What are you talking about? What's an address bar? I don't know what that is.
I explain what the address bar is.
Client: No one will ever know to look there. I wouldn't. Add the web address at the bottom.
