In most places, a property owner must ask law enforcement to trespass the person off of the property before someone is considered legally or criminally trespassing.
This is decided by and highly specific to the local court/prosecutors, so check local practices. I’ve lived in an area where three adjacent counties had three different ways to handle trespassing. One had law enforcement only trespassing, one had owner/manager only trespassing (as in, a random employee can’t do it, only the owner of the property or the person who is on the lease for the land/building), and the last was so loose a patron of a business telling someone to get lost was almost enough for the person trespassing to be arrested.
I used to have problems with clumps. I still do, but I used to as well.
For the most part I now make things in batches. Hot chocolate, tea, whatever. With big batches I can use the mixing bowl and use the immersion blender. Nothing stays clumpy when you have a blade whizzing around at 3000+ rpm.
