Recommended Answer:
Yes, you don't have to wait in line like you were a customer, just go to the side of the register area and when there is a lull in business, ask an employee to inform the manager that you are there for an interview.

Clothes: No jeans, no tennis shoes/sneakers. Slacks. Nice shoes (just not sneakers - they don't have to brand new or anything like that). Button-down shirt or a nice sweater. No t-shirts or polo shirts.

Questions: "Why do you want to work for us?"
"What do you feel are your strengths?"
"What do you feel are your weaknesses?" (always a tough one to answer)
