naw....
you just lost it...
If you brought it with you to wake yourself ....as an alarm..
the natural thing would be NOT to put it back into a drawer ...close it...and forget about it ...once you hit the alarm...
That is much too complex an act for a waking person to contemplate...
Sooo..
you lost it...
set it down somewhere ..
and staff prolly saw it and put it in lost and found...

Don't fret mscion..
Either way ...your disappointment and faith in humanity are equally balanced ...
either a thief took the phone and returned it...
took the money to boot ...too...that was meant for the cleaning staff...I have no doubt..
OR it WAS the cleaning staff that took it in the first place...
OR you left it somewhere else ...setting it down in the hotel...
and someone returned it...staff or guest...

faith and disappointment in humanity ....should actually cancel each other out anyway...there are simply too many people with sooo many motivations, needs and agendas...
and when it comes to the basest level of taking another's belongings..
rarely does a person who DOESN'T need the money ...steal.
Someone who takes something usually sees "risk"...and "need" tends to cancel out the risk of being caught...
So ..I hardly can put such folks in the category of disappointment..
If someone did intend to take it ...they needed the money....

Either / Or ...
its all good...I think..
and it came out well in the end...
