Aibu to think Tesco could have offered me an alternative drink in their £10 meal deal??

I laughed a bit at the sheer ridiculousness of this

Wanted to buy the Tesco £10 meal deal there (main, side, dessert and drinks for 2) but there weren't any drinks left in the fridge for the meal deal. I went to customer service and asked if they were going to be restocking it shortly or if I could have an alternative drink. No stock left apparently and I couldn't have a different drink as the till wasn't programmed to accept it. And, no, they couldn't override this either.

The drinks are usually glass muktipack bottles of Cola or diet Cola. There were some of the same glass mutipacks in the fizzy drinks aisle but were for Coke Zero. No,I couldn't have these.

Of course i didn't buy the other bits as that would have come to over £10 without the drinks so I left it.

Aibu to think this was a bit nuts that Tesco would turn down a sale because of this? And what are they going to do with all that food stock if someone doesn't replenish the drinks soon? No one will be able to buy the deal!

Former supermarket team leader here. They could have let you have a drink within the meal deal.price, as a goodwill gesture, it would just need a few buttons pressing on the till. If they were not prepared to do that, they should remove the meal deal ticket from the shelf. As far as running out of ingredients in the cafe, somebody upthread mentioned allergens which may be different from those labelled in the cafe.
As for gift cards I think something was introduced a while back limiting the amount of gift cards bought in one transaction, as they can be used in scams
