How Cafes Allocate Seats

A small cafe that i visit from time to time has a growing clientele of two types. One category are those who come in for a quick bite over lunch and intend to get a quick meal and depart soon after without spending much time. A different category includes a number who are often alone or in pairs and sit in the cafe occupying the most comfortable seats while working on their laptops or tablets for extended periods of time. A couple of days back, I was there and noted that the lunch hour was very busy but a number of seats were occupied by single patrons whose were occupying spaces for up to four people because of the arrangement of seats.  

To my mind, given the fact that the second category of patrons were bound to stay for long on account of the complimentary wireless service, they were displacing the first category of patrons who were often in multiples but who could not together fit into the space that was occupied by the loungers. This presents a problem because it is obvious that the revenue from the first category of guests would be more than the rest and their displacement may lead to loss of revenue. My solution is that the cafe should consider auctioning the best seats in the cubicles or require that a minimum expenditure be required during the busy hours in order to maximize revenue. This may appear unfair but it is clear that the patrons who come for a quick lunch are the more profitable and therefore pay for both the space and the complimentary wireless service.
