I'm used to that sort of thing for a different reason. I once rented storefront housing as an apartment. I'm also by nature a practical joker. So I put all of my exotic plants in the window (with a curtain behind them), had a professionally printed sign, and put up my computer playing a powerpoint presentation on loop in the window. The sign roughly translated as "Mobile Carnivorous Plants Inc."; underneath it was a picture of a tentacle grabbing a rabbit, with the text, "You have a problem with pests? We have a silent neurotoxic solution!" The video "ad" on the computer discussed our "technology", with lots of reassurances like "Genetic engineering is a safe process" and "All reasonable precautions are taken", mixed in with the occasional statement like "We have no particular reason to believe that the plants will pursue children." There were also random signs to "employees", pointing away from the glass, but which could (on purpose) be read through it, such as "All Employees Must Wash Hands After Handling Virus Samples. If You Cause An Outbreak, You Pay To Clean It Up!" and "ATTN: Who has been putting GM plants in the display window? The display window is for UNMODIFIED plants; GM plants go in the electric pen ONLY."
It's fun to arrive home and have to wait for the confused people whose shopping trip just turned surreal to move away from your front door.
When I ultimately moved out, I posted a sign in the window warning people of the escapes and advised them to ring a (nonexistent) phone number if they saw unnatural movement in the scrubland, and to walk away at a steady pace but "NOT RUN".
Sorry for the brief off topic
