Stop in for a cup of coffee

Good Morning! I saw that happen just Friday after work. I am buying a wheel bearing for my Neon. This guy brings in a battery and says he needs a new one. The guy gets him a replacement and as he is purchasing it he says " I knew it was going bad....it started a couple weeks ago that when you turn the key it just goes wwwiiiiinnnnnggg. Now it won't turn the starter at all it just goes wwwiiiiinng." I bet he is back for a starter
