So, in short, he didn't have a penny in change?
What are you hoping to do about this? You recovered your money I suppose?
Yes, I understand.

But what is the loss?
What are you hoping to do about this?
No, I'm afraid not.
They are not under an obligation to contract with you.
Anybody can refuse to enter a contract with anybody unless they do so for reasons that would offend against the Equality Act.
Come what may, they returned your money when you asked them to do so and therefore the contract that you had was void.
Even if that did amount to a breach though the fact that you choose to get a taxi is too remote from the loss.
I'm very sorry
Of course, if you complain they may well offer something in the interests of good business though.
