It was really strange and unfortunate because we have only had a 10-pound note with us which disappeared very quickly. We got some food for our kid but waited to go to Sainsbury's next door to feed ourselves later. To our surprise, Sainsbury's had no issues with cards whatsoever. Seems like big corporate businesses investing in good servers compared to the local businesses.
Everywhere else we went was fine. These days we keep cash just in case. 🙂

If you do go there, then the last week of August offers fireworks at Flambards and Land's End too. Always a bonus! 🎆

What was your experience at Looe? Is it worth visiting?
