I was in Tesco today and I bought three ruby grapefruits. I like 'em, though it seemed to give the baby hiccups (which is neither here nor there). But the girleen on the checkout had to ask me with a familiar abashed grin, what they were. I said they were grapefruits and asked had she never had one, and she hadn't.
I've also been asked what an avocado was by an embarrassed check out girl in Rathmines' Dunnes. A friend was trying to have a dinner party and was looking for courgettes in Tesco - the response she got from the minion there was 'What's dem?'
Now I admit to a middle class upbringing (Tesco is a thorn in my side when it comes to buying ingredients for dinner parties, or my maraschino cherry birthday cake - No, they are not the same as Glacé!), my mother introduced the idea of avocados to Morton's in Rathmines in the 70's when apples and oranges and bananas were still the only fresh veg available. But come on - grapefruit? I don't do so well on getting my five a day into myself or my daughter (the husband is a carb munching lost cause) but at least I can identify them!
