I'm replying with tongue in cheek here. Super U in Marigot you will find a loaf of bread is the same loaf of bread in French & English, the same roll of toilet paper in French & English, same pound of butter in French & English, same bunch of bananas French & English & so on. On the serious side the check out people are efficient & speak English as easily as French & take dollars as easily as euros. Also bring quarter to unlock grocery cart.
I know very few words in French but have had no problem getting everything there.
