Superdrug interview questions

I had an over the phone interview about a week after I applied then they rang back a few days later asking me to come in to the store for an interview. They first asked me to hand out perfume samples to customers (she asked which perfume i'd be most comfortable selling) which was pretty easy but also asked me to introduce myself and make friendly conversation with the staff on the floor. This was difficult seeing as most of the staff were busy and on tills and the conversation I had was awkward and forced as the person interviewing me was listening in. Then we went to a small back room and she asked me a load of typical interview questions which were ok to answer.
