Can you ......

...just say you are Ronnie Pickering from Hull. That'll scare them.

What if they turn round and say, "my mate's big Vernon from Leeds?"

As others have said, refuse. What can they do? Not required for guarantees.
ASDA p*ss me off for this when you do their price comparison. I just use a false name, address and email address.

Big mistake give an email address and if you don't buy they will offer an e voucher after roughly a week, as they want to get you to purchase.

It's useful knowing a sorting office's postcode for this sort of nonsense, plus how to create emails at one of https://www.dmoz.org/Computers/Internet/E-mail/Spam/Preventing/Temporary_Addresses/

Given my weekly shop is largely from ASDA, I don't see them giving me a voucher for not shopping there.

It's usually xx1 1AA, where xx is pretty much any area.

I haven't been asked, yet, apart from the once to add points to a loyality card I'd forgotten.
Most shops already have my details anyway, because I shop on line a lot

Of course you can refuse. Asda sometimes ask for surveying purposes - it's after I've paid so what can they do if I refuse and walk out with my shopping?

Drop a "NoGo" in a bag!

I was assuming something like electricals and I also forgot Asda are a bit tight with vouchers.

I usually just decline politely with no issues. Only once did someone in Halfords get a bit bolshy over a refund, I said I wasn't prepared to state my postcode and phone number in a public place. I'd already got my refund and just walked out whilst he went to consult with his manager.
