Sitting on a stool in the local pub Tigh Thaidhg with a hot cup of coffee and an empty pint glass in front of me, I glance down at the floor. After a couple of seconds it dawns on me that the ‘tiles’ underneath are not such, but actually a surface painted on with painstaking precision.Further investigation around the set of Ros na Rún proves that all the different rooms in the series have painted on floors, whether it be tiles or wood. I’m curious as to why. A trip to Sweeney Oil answers my question. Around the side of the service station there is an orange door with a battered sign saying ‘leithreas’.
