Why would you kick out a paying customer? If they're being disruptive though it doesn't matter if they bought a coffee. Businesses can deny services and request that you leave the premises. There is very little potential for litigation for discrimination.

> 2. Minimum wage employees shouldn't have to play the role of enforcers. A mentally-ill/drug-addled person can snap and cause a dangerous scene. Getting the cops involved is possible, but time-consuming and a pain.

That's just life. There's no other answer here. You deal with uncomfortable situations and that's all there is to it.

> It's America-centric because we don't have a social safety net for people. In the UK, for example, the NHS has avenues for people to get treated. The homeless you do run into tend to pose a much lower risk, anecdotally.

It would be nice if you knew more about the social services that we do offer people in the United States before claiming something like this. Turn off the news and social media and do your own research instead.

Now that isn't to say (and I honestly don't know one way or the other) that social services in the United States couldn't be better, but that's tangential to the conversation in my opinion.

> We do have coffee shops, but as others have pointed out, many are getting rid of seating. I think a membership route is the only way to enforce something more exclusive.

I emphatically say fuck that. I will go to a coffee shop, buy coffee, sit down and enjoy the coffee, preferably with some friends, and if someone wants to come in and be belligerent and threatening then we'll call the cops or participate in physically kicking them out if the employees can't handle it. I will not live in a world where others are going to disrupt normal everyday experiences and ruin everyone else's lives just because they're assholes or drugged out. Nope. Not me and not the town where I live.
