Touchy.
Customer: "The touchpad on my laptop has stopped working" Me: "You'll have to get it to us so we can have a look." Customer: "Well I can't at the minute and I need it." Me: "OK, well you can plug a USB mouse in it, it'd work then." Customer: "Oh no, I can't be doing with that." Me: "Well you'll have to send it to us then, there's nothing I can do over the phone." Customer: "Oh no! I can't do without it. I need it for my work." Me: "Well as I say you can plug a mouse in." Customer: "Oh I can't deal with this now, I'll ring you back." Go figure?
