Well... our windows are clean and I gave the two employees a tip when they were done. Unfortunately, we discovered a couple of hours later that they left all of our gates unlocked and our dog got out. I was then completely panicked, imagining the worst. Thankfully, we found her (she made her way to our neighbor's house), but IMO, closing/securing gates should be a given when hiring for this type of work. I wish I hadn't tipped... Be sure to check your gates!!
