Each time I hear a corporation is dieing I pop a bottle of champaign and cheer the fertilizer for small business. 

Hard to put genie back in bottle once it's out. 

Bob's a very helpful guy. well when i am in town i go buy a bottle of Silver Oak and meet him at 6pm at his house there on the Reservoir. 

Spend $100 on 5 bottles of Everclear, stand them up outside his door, knock and walk away.

Do I have bottled water available?

I do a welcome gift basket in my entry level apartments and we leave a roll of tp in each bathroom, paper towels in the kitchen, and bottled water in the fridge at every turnover.

If the OP is in the seventies, he needs to bottle whatever it is he's doing, and sell it

But, sugar glass is what they make fake glass bottles that they use in the movie industry.

I do know how much work is involved even with long term tenants, so I'm not sure I'd want to deal with AirBnB turnovers, phone calls, questions about this and that - how do I work the TV, where is the wine bottle opener...on and on. 

I would also include something about the exterior- we have local ordinances about porch/yard furniture having to be outdoor furniture (to keep people from the classic couch on the porch), when and where to place garbage bins and recycling, and keeping the yard cleaned up (no garden or solo cups and beer bottles etc).
