You think you can just take a bathroom break every time you like when you're working retail? Most people I know have worked a retail job or service industry job where they have assigned break periods, and bathroom usage outside of those would be impossible, or very frowned upon.

I guess some people in this industry had parents with enough money to avoid ever having to do a non-tech industry job? That would surprise me.

Some manual or skilled labour jobs would permit random breaks, I guess. But most people I know worked service industry. You don't get to just leave a cash register unattended because your bladder says to.
