Not even for ready money!
Having made such purchases as she desired, and having run rather short of milk, Lady Bracknell then bent her weary steps towards her local branch of Tesco where her eye was caught by a special offer on some rather fine, plump aubergines, one of which, in an uncharacteristically impulsive moment, she added to her basket.
After an inordinately long time spent queuing for the till in temperatures and humidity levels somewhat akin to those prevailing in the average tropical rain forest, Lady Bracknell presented her intended purchases to be scanned by the mysterious bleeping device.
All was going well until the mysterious bleeping device flatly refused to calculate a price for the aubergine. Lady Bracknell understood little of the discussion which ensued between two of the shop assistants, but it seems to her that they key issue may have been a lack of "code" for aubergines.
"We're very sorry", they said, "but we can't sell you the aubergine".
By this stage, Lady Bracknell was in too advanced a state of heat exhaustion to protest. But it has since occurred to her that, aubergines being quite perishable objects, and the fault lying with the shop rather than its customers, it might be preferable to give the aubergines away to those who were entirely willing to pay for them, rather than to have to discard them when they become bruised and soft.
In short, Lady Bracknell is now rather of the opinion that she is owed an aubergine: particularly given that the courgettes she chose to cook with it presented the mysterious bleeping device with no problems whatsoever.
Whilst not wishing to give the appearance of being an out and out technophobe, Lady Bracknell cannot help but point out that, when tills were mechanical, she cannot recall any shopkeeper ever being entirely incapable of calculating a price for any of the items he was holding out for sale.
