My husband did something similar once. Just once. It was more than 10 years ago now, but I still remember the fury I felt. It was mid December.
The kids were small and he was meant to be taking the two youngest to a children's Christmas party run by the sport and social club at his office for young children of staff. There was to be an entertainer, Father Christmas, games etc. and the kids were hugely excited about it. Party was on Saturday morning in the office canteen.
On the Friday night hubby went to the office Christmas party, got very drunk and decided to walk the 22 miles home afterwards.
He rocked up at 8.00am, saying he really didn't feel he could face a children's party. He had no choice though, as the rule was for the relevant member of staff to supervise their own children and I wasn't about to let him disappoint ours. So I bundled the lot of them into my car and deposited them at his office.
He well and truly learned his lesson and was very contrite afterwards.
PS, it was not the same as leaving a hungover drunk in sole charge of them. There were lots of responsible and sober adults and staff there too running the do, and I was nearby doing some shopping.
It was summary justice though for what he had put me through the night before. He didn't get to rest until we had got home that afternoon.
