Input: I work at a gift shop where we sell little trinkets made in China, and we have a penny smasher. It's the bane of my existence. People are constantly turning the lever and making the *clink clink clink* noise all day, every day. Well, I was closing up the store last night when a family came in. I said "Hey guys, welcome in. Just so you know, we're going to be closing in about ten minutes, but take your time" (as you're supposed to say when you work in customer service). There were three adults and about five children all under 10 years old. At 8pm I locked the doors, turned off the music, and brought in our sign that we have outside. At this point I hoped they would've gotten the point and left, but they continued to let their children run rampant through my store that I had just cleaned and organized for the next day (which I had to do over again when they left). 

They pay for their little trinkets and the children all look at the penny smasher and begged to do it. At this point its 10 minutes past closing, so I look at the father and say "I'm sorry but the store is closed now". He says "Can they just smash a few pennies real quick? It's their favorite". I say very nicely "I'm really sorry but it's well past closing and I have somewhere I need to be", which wasn't entirely true, I was just tired from working all day and I wanted to go home. The children all looked very upset, and one started crying, but the father lead them all out and I said "Thank you for stopping in, have a good night". The father ignores me and tries to comfort his crying child. 

So AITA?
