I think in some cases, people are making the wrong presumption here. "Scruffy looking" person can be a homeless person, or a drug addict. And people in these businesses are employees typically, not owners. While many (most?) homeless people may be very tidy, and cause no issues, there is also a subset of homeless people which are mentally unstable. So how do you tell "good homeless" from "worrisome homeless" and lastly from "drug addict"? And if you are forced to make this choice many times per day, and get it wrong, you have customers coming to you and saying "My kid was in your bathroom and it had human shit on the wall and vomit all over the toilet!", how do you deal with that review on Yelp? Trying to claim that without any reason, just randomly, businesses started to become wary is not fair. From personal experience decades ago, I was on welfare. As I appeared somewhat respectable, I was given a discount on the largest room, as long as I kept the landlord notified of issues, vacuumed once a week, and mopped the shared bathrooms daily. The bathrooms were simple, clean, and each tenant used their own toilet paper. One day I entered a bathroom to find shit speared all over the walls. Literally, at least 60 or 70 smears of shit. Apparently one of the tenants had a friend over, he ran out of tp, and so his friend used the wall. I basically had to mop the walls, took hours to get it all off. I assure you that any such incident will make most people extremely wary of allowing anyone that appears questionable, in to use a bathroom. It's not "keep the homeless out" but "keep the scruffy looking person out" along with fear of having to clean that up again, dear god no please!, and oh no I'm going to get a bad yelp review.
