Bladder issues and events

So a lot of us have bladder issues, and there's plenty of advice on how to help (more water, plan ahead, etc) , but sometimes you just need to go and there's no planning to stop it. My question to you all is what do you do for events like weddings, funerals, school meetings, etc? In general I try to avoid situations like this but there's some that would be unavoidable.
