Today's BWOTD can cause alot of confusion for Americans in the UK and Brit's in the USA, as I have found out!
"Would you like a pack of crisps with your sandwich?"
'Crisps' = Chips
So in this case you will be given a pack of Pringles or the British equivalent to Lays, which are Walkers Crisps.
If what you actually wanted was Fries then you need to ask for Chips and unless you are in McDonalds or Burger King, they will be big fat fries and very different!
So when in Britain:
'Chips' = Fries
Confused yet?! So don't ask for chips in the UK unless you actually want fries, otherwise it's crisps!
