First time going into a shelter looking for a cat ...

First time going into a shelter looking for a cat I found online to meet before adopting. I asked someone at the desk who told me immediately that I could adopt her and they could bring her out but I wanted to meet her first before doing so. Couldn t find anyone to help me at the cat area. A vet was checking each animal so I asked her. She seemed irked and opened the back door revealing all the floor helpers in the back room hiding. A guy then tried to help us and when locating the cat he refused to take her out since she had issues and was violent but it wasn t disclosed on the site or on the paper on the cage. I found another I was interested in and the guy laughed and said that one was violent too and he won t take it out. At that point I was frustrated I was walking out but he panicked and told me to wait as he tried to quickly snatch the cat out. Honestly so irritated with how they handle things here and it definitely ruined my trust in getting an animal at their shelter. Hope they retrain their employees and I truly hope they treat the animals better than what I saw.
