[Patrick Rhone doling out tips for those that want to be a Mac consultant][1] hits the ultimate tip:
> Another great value add that gets a lot of bang for the buck — clean the screen. I keep a few of these Klear Screen Travel Singles in my bag. If someone’s screen needs a clean (and, trust me, most do) go ahead and do it. It’s another “extra mile” thing that they don’t think about doing and no other consultant does either (unless they read this, of course).
I’d add that if someone asked me if they could clean my screen (even free of charge) I would flat out say no. But if someone was working on my computer and just cleaned the screen, I’d be pretty happy about it when I noticed it. What a great little tip, and little things like this can be done in any industry — you just have to pay attention.
