I read this in a magazine or heard it in a standup comedy routine somewhere. What could be more redundant and tacky than calling someone on the telephone to ask them what their email is? Bad enough you have to do it for their FAX.
Hmm, if you called them for their address, why wouldn't they talk to you on the phone? Or... maybe you wanted to tell them a joke... ? Imagine if we spent as much time telling jokes as we do emailing them? LMAO
