I think it has to be a somewhat smaller sized shop with the same 3 staff on rotation for the social thing. Applied to both my video store and game store in the 90s early 00s.
Employees got to put on whatever music they wanted.
I should ask my friend who worked there—but there was a lot of fun they had with that. Perhaps, with their musical selections playing on the store speakers, they were even trolling some customers from time to time.
(I know they enjoyed playing John Foxx's single "Endlessly" when Ann Lassley was in the store since it sounded like Foxx was singing her name.)
