yeah i'd basically have no idea what Heidi looks like either. though - to be fair - if i were a store manager at YSL, i'd certainly be expected to know. BUT, with that being said, famous people always look different in real life. and Heidi is rather ordinary looking. it's not like he's Lady Gaga or something. even though i DO now know what he looks like - if i were sat at the table next to him at dinner next week i'd likely not recognize him in person.
SO - if it's a matter of the employee not recognizing him when he came into the store and being fired for that? then he's definitely got grounds for a lawsuit. 100%.
but if he didn't recognize the name "Hedi Slimane" or didn't know who he was or his role in YSL?! then ... yeah. hit the road, employee. you really should know at least these major details about your company.
