Sam's Club interview questions

Basic interview by 2 managers in same day. One was the head of fresh dept and the other was the main boss. He then let me know that i was hired upon completion of a drug test.

I went in early for the interview as I usually do with every job interview. I waited a whole 15 minutes sitting at a dirty table in the cafe. I went to the customer services worker and told them I was pose to have an interview 15 minutes ago. They called the manager and he finally came 14 minutes later, so he was 30 minutes late. He asked basic questions, and said he would give an email confirmation soon. I tried to give him my letter of recommendation, but he straight on rejected to take it. It's clear that I will not get that email confirmation after that. Waste of time, very unprofessional manager.
