The easiest way to resolve this is probably to contact someone at home to wire or transfer the £100 (or slightly more) to the OP. The FCO Consular Office can assist if necessary. And though Embassies can be tough on individual travelers, Consular offices
can be useful - it’s often depending on location or even individuals within the service. I’m speaking from decades of experiences with execrable and excellent Consular staffers, including helping expats get assistance.

Financial Assistance (excerpt)
> We may be able to provide an emergency loan from public funds to help you return home, but this is discretionary and will only be considered in very exceptional circumstances, and only if you have completely used up all other methods of getting funds. If you are eligible, you will have to sign an ‘undertaking to repay’ agreement, where you agree to repay the loan. In most cases, you will have to secure this loan by giving up your passport to our staff, who will then issue you with an emergency travel document valid for a single journey to your country of residence. The cost of this document will be added to the loan. We will not return your passport to you, and Her Majesty’s Passport Office will not issue you with a replacement passport, until you have repaid the loan in full. If you do not repay the loan within 6 months, it will be subject to a surcharge of 10%.
> It is up to us to decide whether we grant these loans – a lack of other ways for you to return home does not mean that we will automatically agree to it.
Lying, attempting to defraud an airline, going transient and moneyless at an airport for three weeks could bring more trouble - particularly the latter, which could land you in a Filipino jail, deportation and blacklisting if you ever wish to return. Don’t dally, contact potential help at home or get to the Consular officials ASAP. Magmadali! (Hurry)
Mind you, in this day and age it’s difficult to believe someone is halfway around the world from home without a single credit or cash card. But here’s the deal: if you’re in your current destitute state because you overspent or blew your funds through a rip-off, mismanaging funds, or even stupidity (bars and bar girls, etc.) and you’re dealing with Consular authorities, don’t try to make up a story they’ll find not credible. They’ve heard it all, and their B.S. detection wetware is generally quite good.
Good luck, go home and learn this important lesson. In the future, laging handa (be prepared).
