When Josie is walking home from the chip shop, he is carrying a bag chips but nothing else. In the next shot he now has the chips and the bag of beer cans he bought before leaving the bar.
In one of the scenes where Josie feeds the horse, the reflection of something (likely a car windscreen) is visible through the trees, in the direction from which Josie came down the lane.
When Carmel offers Josie a bag for his shopping, she gives him a plastic bag, but does not charge him the 22c plastic bag levy in place in Ireland. This was probably a kindness on her part.
