Some dumbfuck people will always knock you or your business just to spite you or ut of jealousy,you can do fuck all about it
my theory is to attract cleints that are going to be happy, and to fuck off the complaining girls, all businesses have them, you really have to expend heaps of energy to make a unhappy client/customer happy, it is not worth it.
at the same time some employees are fucken useless, so u need to hear both sides of the story.
