If you have a bad feeling about something while shopping at Walmart, don’t show your receipt! In many states, it’s legal for employees to ask customers if they’d mind checking their purchases before leaving the store. However, suppose an employee smells what seems like inappropriate behavior or suspects foul play. In that case, detainment may become necessary- after all, “Shopkeeper’s Privilege” laws permit them to force compliance from suspected shoplifters with no repercussions on behalf of themselves as well.
