He then places that in a drawer that has a mail slot in it.  

But, that slot machine was just ready to pay out, she just knew it...and there was that envelope with all that cash in it in her purse...

It's only been a week, but what are my options if they do not return and the RV just sits in the slot? 

While we waited for a slot I drove my son to the same company daycare in the suburbs $50/week cheaper and they had multiple slots open at any given time, Prob 1/3 of the families at this place were waiting on a Downtown daycare slot to become available.I would suggest to anyone to target a Detroit property in near Downtown/Midtown.

The property management company  was horrid and I lost s lot of during the recession.  

Slot machines (and casinos in general) are insanely lucrative.

If you succeed, its very likely that you'll be acquiring homes outside of the park, homes sitting on land or nice homes in run down parks that need to be moved, and if you're in good with them you can fill their empty slots.

In this case, he gave us ample notice to (most likely) fill that slot, however, I'd like to protect us in the future.

But this year all of my STR bookings are for typical vacation time slots of one week or less. 

So, if you have an RV park near by or have RV slots at your property you can hire these people to clean or run the motel for you.
