Stop in for a cup of coffee

My problem is that no matter how well I clean my area, because it’s a shared building, people think my stuff can be dual purposed as storage shelves, work benches or shelters for whatever they happened to have in their hands when they walked by
Like the cars in body shop prison. i keep harassing my buddy the body shop owner,that the t-bird in the corner stall isnt a shelf.
if someone left stuff on my car i wouldnt be happy.

local marina, one outboard mechaniccis meticulous,other one is a slob.
Each has own bench.
Slob works weekend, and uses clean guy’s bench. monday morning, clean guy cleans bench off.straight into garbage can. Tools,parts,hardware. The whole works. Slob never learned.
