Sorry but you will not get a single satoshi without offering something as Collateral.
Your payroll check isn't consider as one and noone will send you funds just because you make "wrong calculations".
By the way, what do you really mean with this?
Edit: Loan could be much £10 if someone could faster payment the loan as then i wouldn't have to pay fees to sell the bitcoin.
I do understand the rules and how things work but It is my last hope in not losing two days wage.
In the UK banks use Faster Payments and if someone was willing to lend me the amount this way then I would only need £10 as opposed to £20 worth of bitcoin in which I would have to sell to then get the funds in my bank account losing most of it via fees and trading rates. Bus fare is only £4.50 return.
