When it doesn’t fit…I have a question.

I recently went to Walmart to buy some cosmetic stuff that was locked up. When the item didn’t fit in the clear plastic box to take up to the register, the associate just handed it to me. Open. What was the point of that? Seriously…why??? What are you supposed to do if it doesn’t fit? What’s the policy? I don’t know why this bothers me so much or why I can’t stop thinking about it. 🤦🏼‍♀️😂😂
