I hope you are keeping a log as to the times and dates you are there doing work. Also all the problems you have had with the HO and other trades with scheduling issues. Show this to them and be honest about what needs to be finished before you will return. I will bend over backwards for some but turn my back to customers that are a pain. Meaning I will only do what I am required to do if they have no respect for my work. Explain to her that what she wants requires a trip charge if she needs you to return earlier than a typical schedule. Sounds like they need a scheduling education or maybe they just don't care. As Dnkldorf said.....always be polite.
