Hey! My first job was in George, so working on the tills there, and so my training was the same as asda staff but more clothes based! aha I loved it. I people were so friendly, and with the training you work through lots of videos and lots of 'quizzes' which are really easy, they are like 'oh if you don't pass this quiz you might not be able to work here' but they're easy!
The people you serve are lovely, just be relaxed and friendly and try to read them, if they're chatty, talk back! Obviously ask them if they have had a good day, and is there anything else you can help them with. Don't be embarrassed or anxious, all of the staff are lovely and are there to help you!
Good luck!
