I came in asking for a product that is relatively obscure. The teenager working had never heard of it and asked the old man working behind the counter if they carried it. He abruptly said no. ""Reputable"" artists don't use that product. It's NOT used in painting. Then he turned around with his back facing me. Unbelievable. I then went to the Asel Art Supply location on Beltline and received wonderful, polite customer service.
