and it's slowly moving to India (and China) anyway .... this is serious as silicon valley is not sustainable too.and hollywood movie is also replaced by Bollywood and Japanese/Korean movie so ....

So I take the best of those - small portions of rich food + wine from the French - fish, seaweed, and soy from the Japanese, and grain-based mostly vegetable dishes from the Lebanese.

Be prepared for higher turnovers, dealing with parents and kids who have no idea how to live on their own (eg using dish soap in a dishwasher). 

@Bruce Woodruff had a dog house, I had a cat house...27 cats, the owner walked away to another house up the street, leaving dishes on the kitchen table and all furniture.

That said, I spend about $80 on each turn re-stocking items like paper towels, dish soap, shampoo and the welcome basket I put out.

That being said, people can definitely be messy and I find myself doing a good portion of the dishes.

People dishing out crap advice or proposing ridiculous limitations are speaking from positions of fear.

I would not allow tenant to do this as they could easily contaminate the petri dishes.

If you want to "rig" something up from outside your windows and all then... again you'll have to verify what your housing owners allow or not (just like a satelite dish).

Set an expectation that no one leaves their dishes in the sink.
