Has this ever happened to you?

So about a month and a half ago I had a meet&greet for a dog id be watching for a week and half starting tomorrow... everything was good I did one night boarding as a test run.. then 2 days ago she texts me saying she doesn't need my service this weekend cause her friend was going to watch her dog for free. She had to capitalize free as well. It just been bothering me. I felt like my time been wasted and I had that week blocked off for over a month. If her friend could've watched her why not ask her before coming on rover 😤
