If you ran a maid service, and you set up a schedule with a customer to send maids out to the customer's house every other Tuesday between 7:30 and 8:00 AM, but then one day you decided to change the time from morning to afternoon, would it occur to you to let the customer know about the change? No? Then you would run your business just like The Cleaning Authority! Change the time but don't tell the customer. And, if the customer called that morning wanting to know why the cleaners were late, would you say, ""Oh, we have you down for this afternoon,"" and if the customer asks, ""Why didn't someone tell me?"" you say, ""You don't have a time constraint on your account,"" then once again, you are running your business just like The Cleaning Authority! If the customer says they should have been called about the time change, and if you just keep repeating ""no time constraint"" as if that excused your lack of common sense, then hey, congratulations - you run your business like The Cleaning Authority! But, if you're like a normal, sane, considerate business owner, you would of course let your customers know when there's going to be a change in the schedule. That's because you know that's the way things work in the real world. If a regularly scheduled service needs to be rescheduled to a different time, it makes sense (to sensible people, anyway) to let the other party know about the change beforehand, now doesn't it? At the very least, you would expect an apology, right? But not if you run your business like The Cleaning Authority! There's no apology. There's no admission of having been inconsiderate, not to mention unprofessional. No, not at all. Your customer was just supposed to ""know"" somehow that you had changed the schedule without warning, and the *customer* is wrong for being upset about it. What an idiotic, ridiculous policy.
