Just came back from the cinema, saw Moana (fantastic movie, btw).
Families with little kids all around us, all with large. popcorn/drink combos or similar.
Now there will always be some spillage, especially with kids. But this wasn't only spilt popcorn or ice-cream. They simply got up and left all wrappers, drink cups and packaging behind.
AIBU to believe that teaching your children to take their trash with them and dump it into a bin outside is basic manners? How can they leave a room looking like a pigsty?
