As long as you have a lot of patience for your average customer.
About 70 percent of your customers come in with distorted ideas about health, fitness, and supplements, if they have any knowledge at all. Be ready to explain basic nutrition concepts and combat ridiculous questions like, "will eating these protein bars make me look like
Jay Cutler?" or... "How much NO2 do I have to take to get big?"
Personally, I couldn't deal with that day after day.
