Get in the habit of pocketing tissues and napkins at every opportunity (in cafes, restaurants, and other bathrooms). To be caught out without extra “toilet paper” is never fun, so making it a point of always having a backup is key to avoiding this drama.
Apps like Toilet Finder can help guide the way! This crowdsourced toilet map gives you access to over 70,000 toilets, and it will even tell you how far it is to the nearest one.
