You have to HAVE PICTURES and SAMPLES in the shop and on your website to EDUCATE each and every customer.
You need to have a SHORT, written explanation (on paper to give to them, also) so that you do not go nuts. If you have a script it will speed the process. Each customer NEEDS to be educated about the process of signage.
If you go buy a new TV, or microwave, or this-that-and-the-other, you generally ask QUESTIONS. Because you don't know. You don't know everything.
As simple as SIGNAGE may appear to you, people DO NOT know about signage.
When they ask you, "I want a sign." Don't get frustrated. Simple explain to them, in very simple terms, Interior or Exterior? Illuminated or Non-Illuminated? Then, WHAT IS YOUR BUDGET? What are you trying to achieve? What is it for? Can I see your design or logo (because this is very important)? You need to see if the art is makeable.
WRITE IT DOWN. Train yourself so you don't go mad. Cuz, customers will drive you mad, unknowingly.
