If you were playing "Deal or no deal" and the last 2 boxes were 1p and £75000. You were offered £20,000?

what would you do?
I know it is very easy to say just go for it when you are not playing
for real money. I would genuinely just go for it. NO DEAL for me..
What would you do.
20k is a new car and a holiday...
75k is the bulk of a mortgage paid
It is a NO BRAINER!
