If the customer is new, that might be the time they are looking for a sitter. If they have been on for a while, I suppose maybe they found and didn't like the sitter, had a sitter turn them down, or had a sitter cancel on them. I would rather take the new person. Also, do you know how you can go look for something online, let's say a music download. You find a cool site - can you browse? Often you can't because you have to "sign up for free" Sometimes you are orces to answer questions that is annoying because we don't even know if we will find something, much less fins something that is worth the irritation. What if, on the music site, you were directed to a music genome project with a bazillion questions. Do we work for this site? No! So if our prospective customers hasn't initially jumped through the hoops before deciding to book, I think that is understandable and not creepy. Plus, you could require something that lends them credibility, maybe vet record? Photo, shot record etc. If they are not inclined to complete their profile once they have booked - and they know you will be their sitter, those are maybe not great diligent dog owners, but it's just as likely that something was more pressing in their life at that time, so we shouldn't automatically suspect the negatives. I have been thinking about this too and what I have decided is that I will make a form with all the Rover profile info, highlight missing bits, and chat about the dog at the meet and greet. I don't like to type into my phone when I am chatting with a customer, but I don't mind a notebook used to "double check" that you have all the information you need for a happy stay. I would live to know what others think. It's an important point, how do the veterans deal with gaps in the basic or even sometimes important info. What if they just legitimately forgot? They will be impressed when you catch the errors.
