Name that fruit or vegetable

So. I'm at the checkout in Tesco. I'm placing the contents of my trolley on to the conveyor belt, in a strict order, because that is what I am like. Fruit, then veg, then other fridge things, then stuff that belongs in the larder, then bathroom and cleaning products. We've only just started and already the checkout girl is looking a little flummoxed. Luckily the boy on the next til is willing to help.

It's a starfruit ...

Oh right ... and what's this? Are these the same?

No no, those are mangoes, and that is a papaya ... in exotic fruit, but it should have a barcode.

Oh, ok ... I'll get the hang of it soon ...

The girl is at least 25, but I figure mango and papaya aren't staple to the average Surreyite. I chip in with a bit of friendly banter about when I used to work in a supermarket, in the days before barcodes and picture tils, and we had to learn long lists of prices and product codes. She is sympathetic, and I assure her that she'll soon get the hang of it.

And then she picks up my one of my peculiar exotic vegetables* and asks what it is.

It's a courgette. I say. Astonished.

Ah! Sorry ... I've only worked here a week ... she offers, as if this is some kind of explanation.

I managed to hold back from advising her that if she ate a few more vegetables then perhaps she wouldn't look so pasty, but it was close.

*Obviously a courgette is technically a fruit and not a vegetable, but I think that would have blown her mind.
