Charging per hour/per day?

[flowerchild]

I know someone who used to charge by the hour and she said she switched to charging by the day because people got really nit-picky "well, I picked her up at 4:15 on Tuesday, so that's $1.25 for that hour plus the other six..." etc.

If you do it that way, I would suggest setting the hourly fee at a set amount per hour or part there of.
