Ask HN: What do you do when the bar is full?

How do you deal with scarcity in social situations?

- When you goto a bar and literally every seat is taken, what do you do? Do you goto another bar, and if so, how do you know that bar also isn't full?

- When you goto the grocery store and there are literally no empty parking spots (and several others are driving around the parking lot), what do you do? How do you know other grocery stores are not also literally full?

- What if you went to the coffee shop to work, but every table was taken? Do you take your coffee and return to your office or home?
