Seriously?
Here's one that epitomises the title of this blog. Customer: "Can you quote me for some refurbished monitors please?" I sent them a 'options' quote Refurb 17" TFT £20.00 Refurb 19" TFT £25.00 Refurb 22" TFT £30.00 They sent an email back Customer: "Can you quote me for four please?" I replied "Which ones?" They emailed back Customer: "Whichever ones are available." #facepalm
