The way I envision it, most slaves aren't allowed to simply roam freely. After all, society has to ensure that just any slave can't simply roam the streets unaccompanied without being apprehended. That privilege is reserved for slaves who have proven that they are suitable for the privilege, and have both intelligence and loyalty.
Of course, the rules wouldn't be binary. A slave like me could leave the home wearing appropriate restraints - a gag that prevents me from speaking intelligibly, a harness that completely immobilizes my arms, and leg shackles allowing 14 inches or less of movement.
A higher order slave in my household would have the privilege of guiding me while I am restrained thusly, walking me on a leash as I bear a large pack on my back. She does not have the keys to my restraints, not that she has any need of them.
She would do the speaking with any store staff and load me and unload me since she has access to her mouth and hands. I, on the other hand, must bear the increasing load in silence. It's not uncommon that these shopping trips take several hours, and sometimes I must be tied to a post outside, forced to stand outside an establishment that does not permit my entry while trying to ignore my heavy load. Instead, I fix my eyes forward and attempt to avoid moving at all. Too much eye motion could be construed as an attempt at nonverbal communication, after all.
