Walmart Cashier interview questions

I applied online on a Wednesday for cashier position (I have very limited retail experience from 10 years ago but they still called). I went in Friday & had a very awkward SAR (Situation - Action - Result) type interview with 2 managers taking turns shooting typical "Tell me about a time you........what was the result...........". They were very nice despite me being called the wrong name twice by one of the managers, who had to be about 15 years younger than me which was weird, it was fairly painless. Some of the questions were so drawn out I honestly lost track of what I was saying mid sentence but rebounded. The odd part was when it was done they went off to "discuss" the interview which meant stepping about 15 feet away with their backs to me but they did come back with a slip to go do a drug test & a job offer. I figure Wal-Mart was my best bet while I'm in college the next year as far as flexibility.
