How do these people not wander into traffic?

I'm a bartender at a small town casino, demographic is mostly old people with nothing better to do, and kids who picture any casino like it was Vegas. I'm constantly amazed at how some of these people can get through life.

Four times this week, I've had people (adults!) walk through the dining area during dinner service, past the dozens of tables of people eating, come straight to the bar, and ask if we serve food.

When we have big parties (50-100 people), we split the bar and have one side do casino/floor service, and the other one waitstaff only, and we'll put up nylon ropes with signage. Apparently this is far too complicated, because I still have:

• People (multiple!) who knock the "Waitstaff Only" sign down, pick it up and put it back, and then obliviously try to order

• People walk past the floor service area to the waitstaff only side, note the sign, then lean over the rope to try and order

• Similar to above, people who walk past the floor service area, note the sign, sit at the closest seat and order, then leave

• And the people who just intentionally ignore the signs because they're entitled (heyy I can be a waiter for the night right? wink wink)

I used to like old people...
