I believe it happens in our company from time to time (I live on the other side of the world, so I don't get to see it). Basically people are encouraged to plan ahead about coming in to the office so that they can make sure there is enough space. It's definitely an issue that some people complain about. It will obviously depend a lot on how the space is managed. If a company likes to see high utilisation of the space (so they aren't "wasting" money), then you will have more contention for chairs, desks, etc. If the company doesn't mind having some empty seats most days, then it will be easy to accommodate days where more people show up.
