Primark Retail assistent interview questions

good informal interview, I went to customer service and asked for the person interviewing me, they sent me to the canteen to wait for them, then when the interviewer arrived she made me feel less nervous and anxious. she took me to a meeting room where she asked me questions such as 'tell me a time you have delivered excellent customer service' and then she wrote it on a piece of paper, then i was given scenarios and asked what i would do in this situation- my scenario was a woman is busy and doesn't have time to use the fitting rooms, what do you do? the interview ended and my mind was at ease after the informal interview had concluded.
