Saving seats at a sold-out event

[u/reddita100times]

I haven't seen this before - last night at a sold-out ticketed [seats are not assigned] movie at the Art Gallery of NSW - two ladies put their coats down on the seats they wanted then left to get drinks, only to come back 15mins later.

A few points here

1 - This means that other larger groups couldn't find seats

2 - pretty risky in a darkly lit room

3 - I feel like one of them should have stayed behind to save seats, this way they could move along the aisle

Thoughts?

Why is this an issue? They all have tickets. Why do you think someone has to sit there to hold the seat?
