I've never had really poor service, but I've had exceptional service. So I bumped it up to 25%. And I was happy to pay it.
In my experiences, the iPad-type devices have a sliding scale for the tip, rather than allowing you to enter in your own tip. I prefer to enter my own tip, as the sliding scale is usually very sensitive.
