Tesco Café interview questions

Didn't check my right to work that I was asked to bring along. There was only 1 interview time slot on the application portal, was told that others would become available but checked back multiple times a day fro a week to see if any would be added and they were not, so cancelled an appointment to be able to make it. 3 other people turned up for the interview at the same time slot I was given so had to wait 20 minutes, others that arrived after me would have waited longer. Woman interviewing complained about the company and how she did not like certain systems within the company.
