Comprehensible staff; they compliment you when you achieve a goal; patient with your accent (if you are a foreigner); people from high position are nice and value your work; staff has a discount on chocolates.
Career advancement is simple depending on where you are. For retail is basically master the language of chocolate and then, become a team leader (and this is decided by the store manager, not by you).
Advice to Management
I do not have any advice otherwise about to work on the career advancement. There are good staff that works hard and want some opportunity to show their skills, but if it is not regarding your job function, forget it.
I applied through a recruiter. The process took a week. I interviewed at Purdys Chocolatier (Vancouver, BC (Canada)).
It was a short and nice conversation. I was interviewed by one manager and she made me feel comfortable. She went through my resume and asked about my volunteering job functions. After that, she started to ask some questions regarding customer service. She also asked some personal values that are too strong in my life.
