Because I need to vent before putting my happy host face on.
I leave seltzer and bottled water in the refrigerator in our Airbnb apartment as well as some cookies, granola bars, etc. I know, and have learned the hard way, to never leave more than I'd want the guest to take. But the vast majority of guests are polite and take a couple drinks, maybe a packet of cookies... I recently had a longer stay guest than usual and stocked the fridge with plenty (I usually leave one or two of each drink per day the guest is staying), then I had a one night guest, followed by a longer stay again. I bet you can guess what happened, right? I left twelve seltzers, six waters, and some beers in the fridge and the one night guests took them all! Plus all the cookies!
And of course these are also the guests who asked for early check-in (or well, didn't ask so much as announced), left the apartment a mess, and did not follow our simple check-out instructions (leave the key and message me that you've gone).
I know, I know, it's my own fault for leaving something I'd be mad if they took but good grief! People sometimes!
