Tesco Customer Assistant interview questions

Found the job through indeed.com. Got a call a few days later, they asked if i could attend an interview that week but i couldn't attend so we rearranged. They were very amienable! Interview was about 30 mins, and the manager asked me 4 competency questions (tell me about a time you didn't agree with your manager, give me an example of how you have worked in a team) and then we walked the shop floor to check my 'customer service' skills. Basically they want you to ask customers if they need any help!
