Ah, I wasn't aware that you attend G3 ...but knowing people's real name and user names here is difficult (I see pictures of Nick McLean in one of your pictures. George?).
The issue in particular at that club is perhaps the general apathy of the members towards change, and the committee's slovenliness in its implementation (where change occurs its usually in spite of them).
In any given night I arrive usually between 5:50 and 6:20. In that period there's usually a few tables going spare on most nights. On the busiest ones, or later on in the evening then it becomes more competitive. Which then leads to the situations where you have to go up to guys and ask them politely to stop using an extra table just to stow their junk on (not looking at some guys in particular...).
With this particular club in all the years that I've been going to it I'd only seen one night where people had to leave due to inadequate space. On that day guys were putting boards across chairs and sticking ones together to make more space. However, that instance was a result of the local Games Workshop doing something stupid and us taking on a few dozen new members for that short time till things sorted themselves out.
On any other night though, I've not really seen any table issues. At least with those gamers who are willing to make their own space (as opposed to ones who turn up, don't see an immediately free table, then leave ...which I have seen happen before).
I've raised the issue of tables with the committee there multiple times over the years. The resolution however is either, 1) that membership isn't a constant, so on most nights the current allotment is fine, or 2) new tables are too expensive to buy (which considering how much we apparently have in the bank, and how much has been spent on new terrain that only a handful of players use, is awry ...especially if there happens to be tables going cheap say from a closing school).
So if there is an issue with either space or tables, its more one down to organisation of the play space (guys taking up areas which could fit four sets of tables, or using more tables than they need to), or a lack of communication ("Hey, can we push these tables together and fit my game in?"). I don't see G3 ever having a scheduling system, due to the cocktail of anarchism and apathy most of the members have. For guys coming off work and just wanting to play with toy soldiers, that's just another level of bureaucracy they don't want to deal with (there's enough mutterings in the background about the implementing of club and council policy in the running of the club as it is. ...You still hear grumblings about the "no flags on council property" incident).
Edit:
Oh and if this is George, and you're referring to a case that I heard about a few weeks ago regarding table space. That would fit into the circumstances of poor management. Where people feel entitled to space, and are affronted when they find out that their claim to it is superseded by people who actually want to play games.
There's the expectation that on most nights we'll be either a deal below, or just under capacity, so cases where people are vying for tables shouldn't be an issue (a bit like the British power grid. If it fails then there's no contingency plan, so let's just cross our fingers that it doesn't and don't think about it). Where any night that we are over capacity we'll either be only just, so people can come up with inventive solutions, or the fallout will be kept to a minimum as the next week it'll be back to normal. Again refer back to the laissez-faire management style that's in place (and the stubbornness that people have towards any sort of change, but ease in which they can fall into complaining about things).
