I think it's ridiculous that it's come to people talking about laws to allow people to use a washroom... and it would never be an issue at a place I'm part of. But.. a law requiring people to let people into their private property.. is not going to hold up if he did try to push it through.
People coming and going from a shippers factory/warehouse/whatever aren't exactly strangers.
To play devils advocate however, having been in the industry for coming up on 3 decades now, I know why some places refuse to let drivers use their facilities;
- Some people are pigs and make a filthy mess of them.
- Some people decide that an invitation to walk through a plant/factory/warehouse to go use the bathroom is an open invitation to wander around going to and from and taking a little tour, and in some cases I'm guessing, "borrowing" products.
- Some people are just plain stupid and have no ability to be respectful or observant, so they walk out in front of forklifts and such, for example.
- Sometimes those facilities are not anywhere near the docks/shipping and receiving, so it means they may need to send someone with you to avoid all of the above.
Now, all that being said, there are
lots of places I've been in my 29 years driving where there are bathrooms right near shipping and receiving, and I present as a clean respectable professional, and I've still be told no. So I'll go piss out between two trailers instead - these same places proabbly wonder why their dock areas smell like piss in the summer months. On a few occasions where it's been a #2 emergency the conversation with the shipper/receiver was a little more blunt and to the point and sometimes they have a change of heart, but on a few occasions even then I've been told no and had to resort to other options.
In my mind, this isn't nearly as dumb as the bc regulation forcing portapotties for each gender at construction sites. Double the cost, almost no benefit. They are private stalls, separation by gender is stupid.
I'm sure it's more to do with perceived sanitation, IE "the men are pigs and the ladies dont' want to use their shitter", although everythign I've gathered indicates that often it's the opposite that's true.
