Most people who work at yarn and craft supply stores are the worst sorts of enablers. You could cynically argue that they're there to sell products, and yes, they are, but many have a passion for some craft.
"Are you storing your extra yarn in the freezer yet? No? Then you're still doing OK," one clerk told me at a yarn shop when I explained that a closet spilling over with yarn was exactly why I wasn't going to buy any that day.
When I relayed that story to a different clerk at a different store, she got a thoughtful look on her face and said, "Hmm... that's a good idea."
But a cashier at JoAnn's took a different approach. I was purchasing not yarn but a bin, in an attempt to bring better order to the chaos that is my yarn stash. When we were chatting and I explained my rationale for the bin, she said in all seriousness, "You know you're going to die one day, right? You need to use it up."
Taken a bit aback (and delighted by the unexpected bluntness of it), I defended myself: "But... I'm working on it, and I haven't bought any new yarn since December."
She was unimpressed. "That's only, what, a month and a half?"
