how do you all go about turning down customers that you get a gut feeling may be a problem to deal with, whether it be payment, delays, poor coordination or people that you don't really feel comfortable with doing electrical work for because they just seem too ignorant or reckless.

do you tell them "i'm not interested in the project, it seems like it might be a pain."
do you lie and say "i'll get back to you on this" or something like that and not get back to them?
or something better


thanks
