Last night I had to chase off a couple from our stores liquor aisle. Between midnight and 7am (noon on Sundays), the liquor aisle must be closed off, done by stringing tarps at each end of the aisle and covering any liquor displays not inside the liquor aisle (per state regulation). It should be pretty obvious that you're NOT supposed to enter but that didn't stop this couple from entering, they had a 6 pack of Sam Adams and a bottle of Bacardi Limon in hand.

Me: Sorry folks, no liquor sales after midnight.
Her: Yeah, we know.
Me: No seriously, you can't buy liquor after midnight, the registers won't ring them up and it's against the law for you to even be in this aisle.
Her: Really?
Me: Yes.

They put their purchases down and leave.
