The Customer is Wrong

I let the branch know that I would be in over the weekend to collect a stamp I had made. I arrived early Saturday morning to find the owner/manager gone and the branch in the hands of an assistant who's first language is clearly not English. He know nothing of the stamp or where to look for a stamp. Told me to go shopping and come back later. I did. He was still alone and still unable to assist. I also wanted pictures printed, with this he was also unable to assist. Gave me a memory stick and told me to put my photos onto that stick and he would give it to the manager. Total self service in this shop. I did so and when I left I told him to tell the manager that I was *&%*#@* dissatisfied with the service. He in turn tells the manager that I swore at him and refused the stamp! Really! Then I get an email from the manager giving me gip for swearing at her staff member and that I had approved the artwork for the stamp and was therefore liable for the stamp but if I didn't want it I could come and collect my deposit. I ask you? Why, oh why would I go back 2x for something I didn't want. Somehow in today's world - "The client is always right" Sure doesn't exist anymore. I will not go back to that branch of 3@1.
