By the way this is the answer i got from tesco's I'm sorry to hear you were not given a frozen bag when there were some behind the cashier. I can appreciate how disappointing this must have been.
In no way are our staff allowed to give any bags away free of charge. I understand you have mentioned you witnessed this, however is it possible that the customer was replacing a faulty bag which is free of charge, or had scanned the barcode on the bottom which automatically registers on the till.

I have seen a cashier giving one yesterday to someone that didn' t buy any frozen, so today i brought my frozen stuff and asked for one and she had the cheek to lie on my face saying that they run out last night and was a few behind her, i felt that i was treated unfairly no wonder i rather go to morrisons or sainsbury.

then why are you even on a deal about frozen food

its not covered in the 5p law as its not a plastic carrier bag

It's worth £3.99

Had them piled up high in a big box in freezer aisle in my local tesco express store. You have to pick up the bag and have it scanned.

Should'nt they be at least charging 5p for this still?

Not bad if you remember to ask when you're at the till!

maybe worth £0.49 at best.

Not in my local superstore

good find op, heat

Thanks for the reminder OP. Wasn't aware of this.

Where's my bag I just spent 60 quid on frozen .....poo tesco sniff sniff

Is it online or instore?

It's worth so much, Tesco needs to use them to keep stuff cool.
