Comment: Free wifi is a curse at some locations as I have noticed. There is a Tim Horton's in the building where my son's condo is located, and every time we decide to meet there for a coffee, there is almost NEVER any table available. You can go by hours later and the many of the same people are there. Given limited seating, often one person is taking a table/booth for four. 

It must be a real dilemma for shop owners and truly a balancing act. I have left a coffee shop where there is no seating and tried to find another one or simply didn't buy. It has to hurt business when purchasing one coffee makes customers feel they can stay for hours.
