What's your view and thoughts concerning working overtime and affecting your going home commute?

I really don't mind it if there is some consistent schedule. If I knew that I have to do 1hr OT for a week, then at least it is something I can work around with my commute home. Unfortunately that is not the case with me. The last work hour of the day is pretty much anything can happen and we may get call for having to do a 15 or 30 minute OT. Sort of like on standbye.

My feeling is that it not worth doing and sometimes changes the plans for my afternoon commute. Plans such as having to take the next train or having to delay a appointment or even totally having to cancelled it because of the lack of time. I had to do that with my dentist when I worked an hour and I cannot get there for my dental work since I had to commute to the train station for a 30mi ride, then commute from the train station to the dentist. Then they charged me cancellation fee which was about the same as my OT pay. If I had the choice, I rather not do any OT at all and just punch out and commute home.
