Bad Attitude of the Manager

I had a bad experience; because of the bad attitude of the manager of the store. There was a misunderstanding that resulted in me walking out of the store unhappy and without the product I wanted. All he had to do was to talk to me for 5 minutes and he would have had all the information instead he decided to ignore me as a client. I believe as a leader and manager of a team you should lead by example and ignoring your clients is a big no-no.
