Here in BC, Canada, restaurants are supposed to be legally required to provide bathrooms to customers if they have sit down dining. But if you go to any restaurant within 100m of a transit station and ask to use the bathroom after buying something, they'll either flat out say they don't have a customer bathroom or it's perpetually "out of service".

I've read some comments on Reddit from restaurant staff along the lines of "I don't give a shit what the law says, the workers deserve a private bathroom free from drug addicts more than the customers deserve one." Which, I can see where they're coming from and I'd probably feel the same way if I had to work 8+ hours in that restaurant every day, but it really highlights the individualistic nature of Western society. Everyone looks out for their own interests only, and have no qualms about screw over others for it.
