- funnily enough i had to buy some from the super market the other day. not sure if i'd done it before - i got a little bit overwhelmed and perplexed by the choice available - there were about 10 types - kitchen foil ffs! i just had to bite the bullet and go for the extra value foil 10m - couldn't really see what the difference would be between that and luxury foil. haven't had any disparaging remarks from work colleagues though or funny looks so think i made the right choice (Y) either that or my work mates aren't into their designer foil.
