In some of the areas he traveled Gaston was a little less liked than in others. The reason for this was his bluntness. He never lied about a place nor did he sugarcoat anything. If a place stank, he said it. If a place was noisy, he said it. If a place had certain improvements that could be made, he said it. Though this made for some very interesting reading, the people who got the blunt side of his dialogue did not always love it.
However, because of his bluntness, when he liked something about a place the way he wrote about it made you want to visit it yourself.
