A straightforward solution will be going for the cash advance loans. You can excuse yourself and visit the nearest Automatic teller machine (ATM), the financial institution, or any other standard bank that would be likely to provide the money. If you are intending to be making use of your credit card, then there'd be a limit.
As you are requiring the amount of money immediately, you will see a small fee incurred by the bank or the financial institution, although that can depend on the type of card that you are going to be using for the Cash Advance Loans. If the person has a credit card, the expense charged will be greater, but there won't be any interest rate attached with it.
The whole concept of the Cash Advance Loan is relatively simple if you going to use a credit card. You set the card inside the ATM Machine, that can then request a security number, which is called a PIN, to verify the authenticity from the card. After it is approved, the card can then be utilized for taking out money in the account(s) of the person. However, there is a separate charge attached to the interbank exchange, so that it would be a wise move to go to the ATM or bank which is of the card itself.
So yes, you can come back inside with full confidence, pay the amount of the bill which is due and leave without any problems, thanks to the cash advance loans. No matter what, there is a solution for everything.
