Re: Cash, always
"Cash.. I use when I have it, but I don't want to carry around £200 constantly to fill up twice a week."
Around town and for much of the time abroad, plastic can work. But when it doesn't, having cash is a good thing. The further away from home you are, the more you should have available. That's not to say that it's a good idea to walk around with a week's pay in your pocket. A bit stashed here and there is safer.
The best place to stash some money might be inside a prosthetic limb left in a suitcase left in a hotel room. Most people will not touch them which could mean even fewer would think to search one.
