This is kind of a vague question, but in general, kings were revered figures throughout history on average. Of course, it is popular now to criticize kings, accentuate their faults and scandals, and deprecate them as tyrants and monsters. But, in real actuality at the time kings were revered figures in their homelands for the most part.
Many peasants believed that the king could cure illnesses just by touching a person and it was common for people to bow or kneel at the sight of the king. For example, King Louis XVIII, who was enthroned after the Restoration, was an unpresumptuous man and he often used to just go strolling around in the gardens of Paris when he got old, and people would bow down and curtsy out of respect for him.
Even in periods of time when nobility was unpopular, in most cases the monarch was still held in awe and respect. For example, in Tudor England commoners were quite irritated by the "court" which were fantastically richer than the average person. So, they would sometimes throw mud or shit at them in the streets if they saw somebody in court dress. However, such treatment was usually reserved for random male courtiers. If the queen herself appeared on the street, everyone would bow.
