Unfortunately there are plenty of business built exactly like that.
One anecdote: there was a group of lawyers that would hire people in wheelchairs to go into stores (e.g. local Verizon dealer) and ask to use the restroom, then once inside the restroom measure everything and take notes. Apparently businesses are not required to make their restrooms available to the public, but if they do, they need to be up to code. So these guys would target chains of businesses that normally didn't allow public into their restrooms, hence the restrooms were usually not up to code. After gathering enough data they would then sue the companies and offer to settle for an amount very close to what it would cost the company to deal with the case in court.
