I'll probably step on somebody's toes here, not meaning to, but I would be more worried about insurance agents than someone who cuts hair. At least he does perform a service to those who want their hair cut.
Insurance agents are selling what? (a promise to pay) for just in case... what? You are not getting anything tangible if you never have to use it.
If you ever drop that insurance because of financial difficulties, then you lost every dime you put into it. Or they drop you if you ever have to use it.
If any of you sell insurance, don't take it personally.
