Foot the bill for Patrick and you to enter (3,3)
I believe the answer is:
pay out
'patrick and you to enter' is the definition.
I can't tell whether this defines the answer.
'foot the bill' is the wordplay.
'foot' becomes 'pay' (I've seen this in other clues).
'the bill' becomes 'out' (I can't explain this - if you can you should give a lot more credence to this answer).
'pay'+'out'='PAY-OUT'
'for' is the link.
Can you help me to learn more?
(Another definition for pay out that I've seen is " Disbursement of money".)
