Haha I somewhat had a manager like that.. she talked about how the job (i was applying for) looks easy but theres alot of detail work, constant changes, and pressure of multitasking and getting things done under a deadline..
But she wasn't rude about it. The Aritzia manager sounded rude, if they were truely not hiring why would she stop and say "wait, do you have experience?"

But like Annie said, I learned that going together with a friend isn't something you should do when applying for any job.
lol yeears ago, I went with a friend to hand out resumes, the FIRST store we went into the manager decided to grill us and popped a few interview questions. And of course being inexperienced and young with no previous job/interview experience we were stumbling...it was quite embaressing and to top it off she condescendingly finishes with, "Oh, and just a word of advice, don't ever go in stores together when you apply for jobs."
haha we were quite dispirited afterwards..
