I was working at Petsmart yesterday, and a customer came in. She had a 10 gallon tank and wanted goldfish. I didnt help her but my co-worker did and thanks to an angry customer complaint from before, we are no longer able to deny fish. The customer insisted on our two biggest ryukin goldfish, and a "suckerfish". I ask the customer "what is a suckerfish?" The cust. said, "you know the fish that eats dirt" My response was "I dont think any fish will eat dirt". Then she says "you know the fish that eats "poop", I said "poop?, I dont think any fish eat poop either" The co-worker finished bagging up the two huge goldfish. As a hobbyist I just couldnt let her buy the 3 fish without a complete explanation of how it is not a good ideal to get those three fish, I then tried to talk her out of it, telling her how they would get to big for that tank and how dirty the goldfish were. The customer start talking bad about us to her husband in spanish, and the whole time me and my co-worker are understanding every single word. She treated us like we knew nothing, sometimes I just let them buy the fish and learn on their own.
