Hi Elisa - Thank you for reaching out. To answer the questions from @Arash69. 1st - I happen to have an Apple Watch, and that literally saves the day for me. I actually run a couple of businesses, so the watch totally helps out with all 3. Obviously, if I am in a meeting, etc. I might be a little delayed in responding, but 9 times out of 10, I am on it right away.
2- Unfortunately, I think there are just a select few "bad seeds". I personally average maybe 2-3 a year. It's just part of the territory when dealing with the public. However, the other 97% are truly wonderful fabulous guests. Sorry I cannot be more helpful in answering your inquiry on how to avoid such guests.
3 - Again, like my answer to #2 - there are a select few guests that are simply "bad seeds". The one thing I have learned is that other people do not treat your property like you do, and/ot expect. It's the unfortunate part of opening your home to the general public (for a lack of a better way pf saying it).
Good luck to you, and just remember that the majority of guests are kind and considerate (at least in my 3+ years experience).
Have a wonderful day!
Jeanna
