Wifi encourages people to sit in your limited number of chairs for hours a day, all for the same few pennies of profit as a customer who walks out immediately or drives away from your drive through immediately and leaves all the resources available for the next customer at the register. Even wifi users who are regular customers and great tippers make for terrible business, simply because of the resources they occupy. If your customers use Windows, you can generally get a decent fraction of them to cycle out by just hiding the power outlets, but Mac battery lives tend to be long enough that that trick doesn't work with Apple using customers.
