Joker is a Norwegian grocery store chain in partnership with Norgesgruppen.
[1] The chain has about 450 outlets, many of which are small convenience stores with a floor area of less than 100 m2 thus allowing them to remain open on Sundays.
After complaints by REMA 1000, a review of the stores in 2016 found that some of them were too large to operate legally on Sundays.
Norgesgruppen took steps to close or reorganize the store layout to bring them into compliance with the law.
[2] The marketing images the stores as being run by "the local grocer on the corner".
