Pubs, Inns, Wi Fi and Stowaways

I approached an interesting note he wrote Mariano Pantenetti especially for the blog.

You may have noticed (or suffered), at some point (usually urgent) when they needed to sit in a bar to do some urgent work, or enter your Wi Fi Notebook, all seats were occupied, even those where he's used against it has no consumption to justify the use of facilities, or alternatively, are on the table the remains of a lean to the clear coffee was drunk at the very least a few long hours.

The free-rider dilemma is the public enjoyment of the property by individuals who use them either on their part fair share as paid or avoiding the cost of their share.

While the case in question in the first paragraph, we are clearly looking at a private good, use that gives the time over which provides the service seems to be analyzed from the perspective of the free rider problem.

The existence of stowaways inevitably leads to a loss of productivity, since many more individuals are "fed" a well thought originally to fewer participants.
Excessive use is made of the property.

Trying to be Pareto efficient is that I ask myself as far as the comfort of who had first occupied the chair does not infringe upon the comfort of who comes second and (after a logical time) starts to pay the cost of discomfort.
Find another bar also has a cost for those who came second.
These costs, eventually moving to the owner of the establishment because the customer alerted of this situation will certainly look for an open bar, efficiently avoiding being the second.

Find a balance then represents a potential improvement in the outcome of any situation that may arise as a Pareto-efficient, where an improvement of one of the agent, it is not possible without harming the other. That is an optimal situation from the point of view of the utility.

Putting on the skin of who should manage a bar, restaurant or similar, one wonders to what extent is efficient free to decide who will occupy a table for a long period of time, such that other people with the intention of eating are far from the place or simply do not enter.
Are these first considered stowaways?
It could be argued that perhaps this first long-term profitability (are customers of the house), while the latter only have occasional use and is difficult to quantify their income in perpetuity.

Some retailers like Havanna coffee seem to have realized this and delivered a limited service (in time) of Wi Fi, forcing the start to continue to consume products for more time or simply leave.
This does not limit the time of those who read the whole newspaper, every magazine, they receive visits and make your office coffee, for the modest sum of about ten dollars the 6HS.

On this situation, seem to have more experience that bars restaurants, experts often drive the customers to have on the table.

I think this is a new consumer and a new way of delivering service, so I do not see a clear answer to the dilemma posed.
Therefore it seems best in this first instance some exercises test, analyze, think about trying not to neglect the customer above all things. But which one? In that two hours is with his coffee and newspaper or waiting.
