RUDE and unprofessional.
I stopped by Michelle's with something to sell and was insulted and literally laughed at in front of many other customers. Told her I would take it somewhere else. She responded with you can't sell that for anything. I am happy to say I have a buyer for one of the five parts at $100. Not too bad for something "worthless".
If you want to look at some interesting old stuff, then go ahead and stop in. If you have anything to sell I would not recommend. Avoid talking to owner is probably my best advice.
