Buddhist monks give advice for lay life

Would you say that it is appropriate for a monk to give advice to the laity in how to live life/dealing with obstacles? Now don't get me wrong, but monks certainly have "safer" environments. They are much less exposed to stimulating sensory input as well as life problems. I am by nature quite skeptical and cannot really take a monk serious if he gives tips and at the same time does not follow these tips (or rather that lifestyle). How can a monk give relationship advice? Sure, the Dhamma gives such, but then it's just intellectual knowledge given by a monk, but that advice has not been practised by him. I think the whole "problem" starts with titles like "venerable" or the admiration of monks/nuns. Again, don't get me wrong, seeing in them a role model and paying homage to them because they delivered proper dhamma is appropriate, but one should always keep in mind that they are UNIQUE, COMPLEX (in that they think, feel and do good, bad and neutral things) and FALLIBLE. Anyone made same experiences? Advice? Opinions?
