Working at a grocery store is as pleasant was working at a grocery store. You're either going to love it or hate it. You much know this before interviewing for this job. Management will always have a smile on their face when in the pressance of customers. Its when they pull you in the back, or call you to their office, that you see their real personalities. The main thing management wants from you is to please the customer any way possible. Don't just point to where something is, walk them there.
