Harsh Plastic

I went there to get lamination of an expensive art print today. The owner told me that they wont take liability to which I understood and agreed. When i requested him to request his staff to be extra careful and supervise. He started telling me that they do and we dont have just this work so get it done somewhere else. He mistreated me by ignoring me and telling his staff to talk to me rather than addressing me. He then started stating this is not govt work where you tell me to supervise. This is not my work. I felt bad and left. Basically they ill treat there customers. They are not pleasant good human beings. I was never humiliated so much before. I would give them minus points for this.
