I no longer expect critical thinking in some corners of MN, but could it be that advertisers are pitching this at Black consumers TO GET THEM INTO SHOPS?
Bar Morrison's half priced whole salmon, I don't buy meat in a supermarket and neither does my family. We buy my meat from the English butcher on the high street, because he sells everything including that homemade bbq sauce someone in the community makes.
All my seasonings come from the black or Asian shop. And ground provisions come from the black shop.
I can see why Tesco would have my face on TV, because I imagine he'll want to see me every once in a while. Maybe some smarty pants in advertising has realised that the goods in the international aisle are not shifting, so it makes sense to appeal to that market?
