"I'm sorry to hear we did not have the Champagne you wanted last time you was in store. I am pleased to say we do now have this in stock and it is at the offer price.
I'm sorry you was not able to spend £40. However I will not be able to honor this as all the shops must be £40.
I hope this helps."
The misuse of the term "you was" and the spelling of "honor" imply an American background. So why could they not offer a rain-check, which is standard in the US when something on offer is out of stock? My request was not even acknowledged.
The lack of a £40 coupon for this "shop" means that I do not qualify f or a £15 discount for a later purchase.
"I hope this helps". Er, no it doesn't. Tesco's is next door, and they sometimes have the same champagne on offer.
