Pros
Felt more personal than huge MegaMart type place. Treated with respect by employers generally. The store does not feel as intimidating or as sterile as other larger stores which makes it much less stressful on the employee and more conducive to lively enthusiastic employees.
Cons
Even with great customer feedback over a duration raises are not common or only barely incremental. Also even after working for a long duration their with a more specialized position you may still have to when times get tough just be a regular cashier. Sometimes they will let entire departments go untended by staff and just run cashiers at the front of the store. This is unfair to the customer who has to struggle for help and very stressful on the employees.
