You really shouldn't shun clientele, just politely direct them.
Geeze.... if you think that was shunning, you should probably run for the nearest door now while you have the chance.
Kidding aside,
@Nocturne really didn't say anything that shouldn't be done as a matter of course. If you're stuck, the manual should ALWAYS be your first port of call. It's jam packed full of not only useful, but vital information. If you don't understand what's in there - which will happen now and then I guess, then the forums are a great resource to help you get to grips with things.
But really, if your stuck on on anything, then it'll be much quicker for you to look at the manual....after all, you can search and read it for 5 minutes, or you can post here and may wait days for an answer.
