I actually had a head teller do this to me obnoxiously the other day. I asked for halves when I was in a rush at a bank. The one teller says: "I have $2.50 worth, let me check what the drive through has". With that the head teller goes to the drive through and comes back and says: "they have $14 worth and this teller has $2 worth" (about the original teller as the head teller is putting one off to the side. The original teller then says: "I had $2.50 worth". The head teller then says: "I'm buying this one because it is silver. It's 40% silver so I want that one" and then they sell me the rest. I don't have an account at this bank and I was running late and quite frankly I was absolutely in shock at the poor customer service of this swarmy head teller. I've been letting this exchange stew in my head for a few days.
On the one had, it was a single 40%'er a day after I had a box with 49 silvers in it, so in the grand scheme of things it is of no consequence. On the other hand, at this point it isn't even about the silver. It is about this dude having some kind of power trip and overtly putting his desires ahead of serving a customer, while directly saying as much. This dude was out of hand. Since that day I have gone to a different branch of the same bank and secured the contact info of the regional manager for this bank. I am seriously considering making that the most expensive 40% that teller has ever purchased. I am all for tellers sniping silver. But for a head teller to snipe silver out of a different tellers tray right after that teller said he was going to give it to a customer is crossing the line. Decisions, decisions.......
