LOL.... no cashiers. No registers.
Exactly. No doors, no windows.
Most non-membership stores are simple.
You own title to the merchandise you buy as soon as you pay cash or swipe the c/c. Those stores have no legal right to stop you on your way out the door and check your receipt, etc.
This is why I WONT JOIN any membership club. You agree away your rights and allow them to treat you as a thief. at the door.
Simple.
