Prank calling a UK store

A little request for a prank call.

A while ago I saw a video where a guy prank called an asda store by getting a woman to say on the speakers to the whole store, 'Tess-cosis-cheaper', by asking if a family member by that name was in the store.

What I'm asking is, will asda fall for it again or will another store fall for it.

Well asda (wallmart) has already taken a beating, lets give the no.1 bastard store a go, you can tell i HATE Tesco, it would be nice to see a prank call of me... yes im flirting again... by that i mean call me (random!)
