Pros
Honestly, one of the mediocre jobs out there, you go in, do your shift (safely!) and leave. The best part of the job was the people within the store, including an excellent manager who was always upbeat and bright. She also helped welcome me back after maternity leave when I was struggling. Benefits are great too, you have to do the monthly huddle in which can give you points on a voucher etc.
Cons
We were connected to an M&S franchise. I found it a struggle when customers came to complain and had to explain we weren't M&S but a BP, especially when it came to people not bringing in IDs for restricted item selling. There was an incident that we struggled to work around, which brought the decision to leave, and nothing was really done about it apart from 'You leave the shop floor whilst the customer is around,' and that customer stayed for 30/45 mins.
