Pros
Amazing experience, the people are friendly, patient and always willing to help out.
It's a place of passion. So many areas to dip in and learn new things. LEGO, Pokemon, Toys (Warhammer, Dungeons & Dragons), Video Games, Minerals, Fossils... you name it.
Cons
Work can get chaotic and convoluted at times, but it can be navigated and understood with enough patience.
