This is a learning experience for me.
I also noticed the person who I dealt with wasn't friendly to me. Is this common when you sell something to a store like they look down on you / belittleness etc? He looked dead serious about the price and didn't want to waste time. Instead he managed to chat to another girl who stood next to me trying out an old camera. I'm still a "customer " to him. And I was thinking of upgrading to a new camera once my financial situation has sorted out. If that's how he treats customers like that I will shop elsewhere.
