*Never* do CSS tweaks over the phone and tell the customer to refresh and approve the change. This will lead to endless tweaking andlong calls at any hour, and further trivializes your work by making it look like everything can be done instantly. Better to have them send you the changes they want, then send them an update later once they have been done—perhaps with a bit of a delay to further stave off the sense of instant gratification.

Also, if they keep requesting changes to changes after you’ve done what they asked, be prepared to let them know that future changes will incur an additional fee.
