my first impression of coin dealers her wasn't too good. stepped into this small shop which was however impressively adorned with slabs and slabs of world coins at the window display. $3 per coin in the junk bin... none of them were worth even half to begin with and they were pretty unattractive and common stuff anyway. asked to see a slabbed Victoria 1/2 crown in a glass display and the man told me unless I had the money for it he wouldn't take it out. After browsing further he got impatient and started admonishing me for god knows what. never going back in again. suppose its a dealers' complex, albeit probably a 1 in a million type of complex.
Those dealers don't deserve the business of you or that kid if they treat you like that. I have a shop that treats every new face like a criminal, always an eye over their shoulder. But they don't do the antics that this shop did. And once you become a regular, they will be a lot more relaxed towards you. They know I have zero interest in bullion so they don't put it on priority while I am in.
That's an awful way to run a retail business. You would think all the cameras and the threat of prosecution would be enough to keep people honest, and to keep dealers civil. I have two LCS in town. One will let me go behind the counter and pull out what I want. The other is equally trusting where just last week I stopped in and the owner, knowing I like Saints, went to the safe room and grabbed 20 slabbed Saints, some common, some rarer. Then he left me up front to go through them as he went back to the safe room to grab 10 more. Admittedly I am more than just an occasional customer, having emailed both about coins and other matters, but it goes to show that poor customer service does not have to be the norm.
You should have taken a look at their "bullion bars and medallions" when she asked you, even if you didn't buy any that day. It's all about building relations.
