Hmmm, if he already said the money would go in tomorrow, maybe you should leave it. Of course, tomorrow is Friday, so if it doesn't go in tomorrow it won't 'til Monday. Can you live with that? Give him a chance to do what he said he'd do, if you can.
Or, maybe a short email...
I hope you enjoy the movie. I won't be in tomorrow night, so we'll talk some other time. The account will be fine after you put in the money tomorrow.
