Then why do you think there is such things as comment cards? Lolz
surely there's a difference in customers saying they were happy with their service today and asking for advice on how to spend advertising dollars.
otherwise, you would never need professional advice on anything - just ask any random moron on the street, which i suppose, is what you believe. "lolz"
its really simple
either you understand what im saying and know im right, or youre an idiot.
this is not really debatable.
if you really, really, deep down, think successful business owners ask the barfly for advice on how to improve their bar, then youre an idiot.
