Spoilers Pharmacist talking to Mimouna
Undoubtedly there is a lot of antipathy towards North African migrants and their descendants in France. However I dont think the pharmacist telling Mimouna to take three yellow pills and two red pills a day was being racist as her son Karim said. Here in Britain pharmacists says this to customers of all races all the time. Firstly because the name of the medicines are long and complex and secondly because anyone in a position of authority in the UK especially in a white coat can be very patronising towards ordinary people.
