Hey guys, I had a show where a guest came with an older ice cream scooper that was leaking and the metal was corroding from the liquid inside. She doesn't have a reciept. She said that the product had a lifetime warranty back then. I'm 2+ months new at this and am not sure how to go about this any advice? PLEASE!! P.S. I was kind of bugged by the fact that she just complained to me in front of everyone at the show. I 've been wondering if it affected my sales any.
